The common perception regarding what happens when two objects of equal sizes but unequal mass are allowed to fall freely towards the ground is that - both the objects make contact with the ground at the same instant.

This is attributed to the fact that the acceleration of both the objects towards the earth are the same for a given height. This was the reason for Galileo's expirement.

But the above fact ignores the fact that each of the three objects are attracting each other. In particular, the heavier object also attracts the lighter object, thus decreasing the distance between the lighter object and earth.

Note : I am ignoring the fact that the lighter object would also attract the heavier object (but to a lesser extent) and since the earth moves approximately in the same direction as a result of the attraction from the other two spheres, that is also ignored. Otherwise the earth can be said to move diagonally towards the heavier object (again to a small extent).


I have included an illustration showing the movement of the lighter object towards the heavier one. Gravity Free Fall - Scenario 1


As such the lighter object should fall first is it not?

Note : Generally, the two objects are placed close to each other (the distance-d between the objects is lesser than the height-h from the ground - 'd < h' ).

Continuing with the same logic, I have the following understanding :

When two spheres of equal size but unequal masses are allowed to fall freely towards the ground -

1.) From a height greater than the distance between the two spheres, the lighter sphere makes contact with the ground first.

2.) From same height as the distance between the two spheres, both the spheres make contact with the ground at the same time.

3.) From a height lesser than the distance between the two spheres, the heavier sphere makes contact with the ground first.

Note :

a.) The ground is also a sphere.

b.) The distance between the spheres are measured from their centers.

Is my understanding correct?

I also found this Phys.SE post. Which speaks of a scenario where in only two objects are involved. My question is similar to it.

PS: I have blogged about it before as well, saying it is so and also elaborated on two other cases ($d=h$ and $d>h$).

    $\begingroup$ Consider that the mass of the Earth is much much greater than the mass of the other objects is likely to be. This ensures that any movement of the Earth is negligible in comparison to all other distances involved. If that were not the case (all 3 masses were comparable) then you see that each body moved towards the center of mass of the other two. Take a look at the Three Body Problem, maybe? $\endgroup$ – Pranav Hosangadi Oct 29 '13 at 16:25
  • $\begingroup$ @PranavHosangadi : What I am trying to say is- regarding the point of impact, the three conditions above hold good for all combinations of masses, not just because the earth is massive. The three objects are moving towards the center of gravity of the system. The system in this case involves the three objects. In case of the earth and two objects, the earth's mass implies that the center of gravity of the system is close to that of the earth, resulting in the earth moving a negligible distance. Thank you for the link. $\endgroup$ – Ravindra HV Oct 30 '13 at 7:16
  • $\begingroup$ In practice, assuming both objects have the same shape and density distribution, and dropped from the same orientation, the heavier object should hit the ground first. $\endgroup$ – Cruncher Nov 22 '13 at 18:57
  • $\begingroup$ What do you mean by 'orientation'? My understanding is that the heavier one will make contact only if the height (h) is lesser than the distance (d) (h<d). If h=d then both the objects make contact at the same instant. If h > d, then the lighter one would make contact first (the heavier object attracts the lighter one laterally thus decreasing the distance of the lighter object from the vertical, w.r.t the illustration above). I have blogged regarding it in detail. Search for "Effect of gravitational force upon three objects of unequal mass". It begins with a warning. $\endgroup$ – Ravindra HV Nov 24 '13 at 6:48
  • $\begingroup$ the effect is very small because if M3 is more attracted by M2 than M1, this also brings M3 closer to M1 . $\endgroup$ – user46925 Feb 20 '16 at 2:19

It helps if you consider the components of the acceleration of the smaller planets due to the gravitation force of each other planet. Here is a rough diagram showing the components of acceleration for each planet, assuming the largest does not accelerate due to its large mass:

enter image description here

The red arrow shows the component of acceleration of a planet due to the gravity of the largest planet. The green arrow is the component due to the other planet (not the largest).

Now, consider the bodies accelerate only by the red components of acceleration (i.e. ignore the gravitation effects between the two smaller planets). As the centres of gravity for the smaller planets are the same distance away, the motion of the two smaller planets will be perfectly symmetrical, and both planets hit the largest at the same time (assume smaller planets have similar radii/size).

Now, let us add the effects of the green arrows (i.e. the gravitation effect between the smaller planets). The angle between the red arrow and the green arrow is less than 90°, so this means that the green arrow will add to the acceleration of the planet towards to largest planet. Let us assume that the green arrows are sufficiently small so that the total component of acceleration perpendicular to the line connecting each small planet to the largest planet does not cause large rotational effects about the largest planet (i.e. effects such that the small planets do not travel in approx. straight lines towards the largest planet, complicating matters, and possibly throwing the smaller planets into orbit around the larger!).

The less massive planet will have a larger green arrow, and the larger of the two green arrows has a greater contribution to the component of acceleration in the radial direction (radial, as in the line connecting the smaller planet to the biggest planet). This means that, in this instance, the less massive planet is accelerating slightly faster than the slightly more massive planet towards the biggest planet. From this, it is sufficient to assume that... drumroll the smaller planet will hit the largest planet first!

This is true for all values of d and h, assuming the values don't cause the smaller planets to collide with each other first, and that the path between each smaller planet, and the largest planet is approximately straight. (i.e. d is above a critical value)

The gravitational forces acting on the two objects due to their interaction when 5 m apart have magnitudes of approx. 2.7e-2 N, giving initial horizontal accelerations of approximately 2.7e-8 and 2.7e-6 m/s^2. In the 1.49 s it takes for the two objects to reach Earth, those accelerations will change negligibly. The smaller mass will travel along a very slightly longer path but will have a very slightly higher average speed - why should the horizontal acceleration affect the vertical acceleration?

At a latitude of 45 degrees, the value of g varies by approximately 0.001 m/s^2 per degree latitude, which means that, if one mass is dropped from a point 5 m further north at that latitude, then its value of g will be roughly 4.5e-8 m/s^2 lower than the value for the other one, and it will hit the ground very slightly after the other one.

That's if one doesn't hit a can of worms.

$\endgroup$
  • $\begingroup$ Sorry, not sure if I can follow you. But basically the idea is that while it 'appears' to be horizontal, with regard to the center-of-gravity, it contributes to the acceleration towards the center. $\endgroup$ – Ravindra HV Nov 18 '16 at 21:41

$\begingroup$

Two objects of unequal masses, ignoring other forces would be attracted by at the same velocity provided by the acceleration due to gravity. But objects with less mass are generally less dense, causing other agents to friction it's movement to the ground, while object which are more dense and have more mass will be more rigid to that force. This would cause the object with more mass to reach the ground faster than that which has less mass

$\endgroup$
  • $\begingroup$ If I understood you correctly, you said that - a. its true that objects are attracted at the same rate independent of masses if we ignore forces b. you said that objects with more mass will be rigid - do you mean inertia ? c. but then you also said the object with more mass will reach ground faster, which (which contradicts b.) What I am trying to say above however is that - what falls first 'depends' on whether the 'angle' made by the falling objects to the reference object is acute, equilateral or obtuse $\endgroup$ – Ravindra HV Mar 28 '15 at 15:57

Only if the situation is symmetric and the masses are aligned like an equilateral triangle all masses will meet each other at the same time:

  • $\begingroup$ The scenario I considered was where the three bodies were at rest without the influence of any external force and all the three were on the same plane. In your case, what you mentioned is the same as what was mentioned above. However, in the second animation, in case of the above one, two of the objects make contact before the third one comes in - which is similar to what I said in case of an isosceles triangle but they are not on the same plane. In case of the last animation, none of the three appear to start from rest. Which is also a different scenario from what I am considering. $\endgroup$ – Ravindra HV May 14 '16 at 14:54
  • $\begingroup$ When I wrote the questions, I was not thinking of elastic collisions like you have. I only focused on the first point of contact. But I am still not sure if the collisions will result in circular motion. If they all start from rest, their paths should be linear is it not ? If you think about it, any three objects interacting with each other with no external influence will follow a path as if they are on the same plane. There is no scope for circular motion. They can never gain more energy than what they initially had. $\endgroup$ – Ravindra HV May 14 '16 at 15:16
  • $\begingroup$ The center of gravity between the three masses cannot shift from what it was before. Their paths are initially linear and as per my understanding even after collision they cannot acquire a path that will either take them back to the initial state (and start all over again) or set them up again for yet another collision. In any case, the animations are interesting. Thanks! $\endgroup$ – Ravindra HV May 14 '16 at 15:16
  • $\begingroup$ The scecond and third animation show the same scenario, the difference is only the trail length. They do not show any collision, neither elastic nor inelastic. And they are on the same plane, z=0 for all bodies. $\endgroup$ – Yukterez May 14 '16 at 17:25
  • $\begingroup$ Ok. It makes sense now. Thanks. But the red and blue points do seem to make contact and deviate after that. That is what i meant by collision. Also towards the end of the animation, the center of gravity between the three objects appears to have shifted. Is it not ? $\endgroup$ – Ravindra HV May 15 '16 at 21:30

$\begingroup$

Well the purpose of the statement "both the objects make contact with the ground at the same instant" is to convey the fact that the gravitational acceleration does not depend upon mass of the falling object.

The experiment could have been done by dropping two bodies at different times and measuring the time they took to reach the ground and that would have given same results.

What you are pointing towards is - negligibles. Yes, there can be negligible effects due to simultaneous fall of two bodies but that does not change the message that was supposed to be conveyed.

$\endgroup$
  • $\begingroup$ Perhaps, the intention was indeed to state it in spirit rather than in literal terms. However, it would still help to note it down somewhere, just in case there is a scenario where the casually stated sentence could prove costly. $\endgroup$ – Ravindra HV Feb 18 '17 at 13:41
  • $\begingroup$ @RavindraHV: The angles you have shown are totally out of proportion, just to over highlight the effect. In practical, the lines are nearly parallel and the effect would not even be measurable to cause any damage. $\endgroup$ – kpv Feb 18 '17 at 16:34
  • $\begingroup$ While I cannot indeed provide an example, still it does not imply equivalence. It's always worth it to keep the detains in scope. $\endgroup$ – Ravindra HV Feb 18 '17 at 17:45

$\begingroup$

If the mass of both the objects are high such that air resistance in negligible in them then both of them will touch the ground at the same time. If the body with smaller mass is so small that air resistance can't be neglected then the body with heavier mass will reach the ground faster.

$\endgroup$
  • $\begingroup$ The point I am trying to make, is that although the earth attracts all objects at the same rate, the heavier objects attract the earth itself towards themselves as well, more so than the lighter objects. If the two other objects are far apart then its not easy to tell. However if they are far apart, in the best case at opposite ends, then its easier to tell. If the sun were to be shrunk to the size of the moon, and then the sun, earth and moon were placed at equal distances from each other, then the sun would definitely pull the earth towards itself far more than the earth would pull the sun! $\endgroup$ – Ravindra HV Feb 15 '15 at 19:05

Here is the output from a program I wrote - it analyses which of the to masses between mercury (mer), venus (ven) and earth (ear) start coming closer (the third point in my question above where the heavier object is noted as making contact first - the earth is the reference ).

From the below output we can see that after starting off with the same distance between them, venus and earth are closer to each other than earth and mercury.

The log file abbreviations are as follows :

the cog-dist - is the distance between the centre of gravity between two masses.

gvt-a-to-b is the acceleration due to gravity - exerted by body a on body b. I mentioned the calculation logic only in the end calculation since the max 30000 chars was reached otherwise.

    $\begingroup$ The output here is completely meaningless without the code itself (for us to run & verify and/or criticize). If it is too long, consider posting the code at a code hosting site like github $\endgroup$ – Kyle Kanos Mar 29 '15 at 17:33

    $\begingroup$ I dunno, this isn't a peer-reviewed venue, I don't think we necessarily need to see source code for all results posted. That being said, it certainly wouldn't hurt. The bigger issue I think is that long lists of numbers are not useful. This would be better off as a visualization of some kind. $\endgroup$ – David Z Mar 29 '15 at 18:21
  • $\begingroup$ @KyleKanos will try posting on github. But all the details are there in the post above for whoever is interested in verifying the same by writing their own code. $\endgroup$ – Ravindra HV Apr 2 '15 at 19:19
  • $\begingroup$ @DavidZ it'd be easier for me to post the code than turn it into a graph. Will post it if I make one ! $\endgroup$ – Ravindra HV Apr 2 '15 at 19:20
