Why doesn't air below a falling object balance its weight? [duplicate]

Consider the following scenario: a body is dropped and it hits the air molecules below it with a force equal to it's weight. By Newton's third law, the air molecules below should exert the same force ...

Newton's third law confusion [duplicate]

If A exerts a force of 200N on B, then by newton's third law, 200N would be exerted on it. Similarly, if B exerts 100N on A, by newton's third law, 100N would be exerted on it. Therefore the net ...

Why is an object pushed when you push it? [duplicate]

According to Newton's third law, if I push an object the object should push me back with the same and opposite force. So there should be no net force, which means that it shouldn't be displaced (...

How can any object move? [duplicate]

If an object A exerts a force on another object B, an equal and opposite force will be applied on object A by object B, so that means for a force to be applied on object B by object A, a force must ...

Newtons third law explanation on a push of table [duplicate]

I read this example of pushing a table with your hands. So the force is applied on the table to push and the table exerts the same amount of force on our hands. My question is, if the forces are ...

If every object could give an equal and opposite force to what we apply then why do the objects exhibit translatory and rotational motion? [duplicate]

If I push a block on a frictionless surface with enough force, it begins to move. Shouldn't it be standing still if it exerts an equal force on me as per 3rd law?

Doubt on Newton's third law of motion [duplicate]

Okay, so if I have 2 blocks of different masses 4kg and 2kg placed side by side with possibly a distance of 1 molecule between them (sorry if the diagram doesn't show that). There is negligible ...

How does Force translate a body if each molecule if pulled with a force,pulls the next molecule and still the body moves? [duplicate]

In diagram 1,F pulls the body. The molecule in contact with F gives an equal normal reaction opposite to F,the same happens with each molecule,how does the body move then? In diagram 2, is the logic ...

Newton's Third Law? [duplicate]

I've recently met with this new law and the way my teacher worded is so off for me. Shouldn't the equal and opposite reaction cancel out the action because they are equal? Apparently not? Why?

Is Newton's third law always correct?

Newton's third law states that every force has an equal and opposite reaction. But this doesn't seem like the case in the following scenario: For example, a person punches a wall and the wall breaks. ...

If something that is moving at constant velocity has no net force acting on it, how come it is able to move other objects?

Let's say 10 kg block is sliding on a frictionless surface at a constant velocity, thus its acceleration is 0. According to Newton's second law of motion, the force acting on the block is 0: $a = 0$...
