Why does the ball in Galileo's double inclined plane experiment reach the same height?
Why does the ball in Galileo's double inclined plane experiment reach the same height? I know how to show it by energy conservation law but am unable to prove it by the equations of motion. Can anyone ...

Why for motion planning of quadrators the goal is to minimize the jerk/snap?
In motion planning for quadrators the optimization goal is sometimes to minimize the (norm squared of the) jerk and more often the (norm squared of the) snap. Can someone provide an intuitive and ...

Newton-Euler approach for the equations of motion of spherical pendulum attachted to a moving body with 6 degrees of freedom
I would like to obtain equations of motion for a spherical pendulum suspended from a (6 degrees of freedom) moving body (generalization of a simple pendulum on a cart) using Newton-Euler approach. ...

Question of ball falling down.Difficulty in understanding the formula
A ball is thrown upward from the top of a tower 40m high. u = 10m/s.Find time for it reach AD.
g = $10m/s^2$.
Taking upwards direction as +ve and downward as -ve.
u = +10m/s.$g=-10m/s^2$.s=-40.
$-40 = ...

Velocity of object on extremely low air density?
If we derive velocity in air when setting air resistance to $kv$,
we'll get
$$v= \frac{mg}{k}\left(1-e^{\frac{kt}{m}}\right) $$
and if air density goes to $0$, $k$ will also goes to $0$.
When $t=T$ (...

Rotation as an example of symmetry in classical mechanics
I modified the question because it was confused.
On my book there is this mathematical definition of symmetry transformation:
"The equations of motion have a symmetry, if the solutions of the ...

Do the equations of motion have specific characteristics?
I solved a classical mechanics problem in a form somewhat like this:
$$x(t)=t^2+5t$$
$$y(t)=t^3$$
$$z(t)=5.$$
The problem asked me to find the equations of motion of an object.
From my ...

Control system with equation C = A*x + B*dx/dt
This question came up in a computer science / robotics exam and I still don't know the solution for it. I figured out that it's classical mechanics related, so I thought this might be the best place ...

Laws of Motion: Acceleration to be applied on a free falling object to reduce velocity to 0
Assume that an object of mass 'm' is falling to the earth.The force acting on the same would be F = m*g = 10m (assuming g = 10m/s^2). In this case the velocity of the object at time 't' = 10 seconds ...
