According to Newton's Third Law why is there a difference in movements between collisions of different mass (please read description)?
When an object of some mass hits and rolls towards another stationary object of the same mass, the ball that was rolling stops. However, if we use the same ball from that scenario, and roll it at the ...

A block experiencing a constant force collides with a stationary block
If a constant force is exerted on a block 'A' on a frictionless surface and if it collides with a stationary block of a lesser mass on the same surface (let's call it block 'B') then upon the ...

Is there a difference between impact force and force coming from Newton's second law?
So me and my friend were having a discussion today that why should our legs break if we jump off from a taller height like 20 meters than if we just jump from a mere meter. We both agreed that our ...

Why does $g$ become 0 for this question?
A body went up for $4 \;s$ in air and then down for $4 \;s$ with the total journey of $8\;s$. Now, the graph above is a $a-t$ graph for the statement.
My question is that why does $g = 0$ when the ...

How do I find out if the normal reaction in a given situation is impulsive or not? [closed]
For some cases, like two blocks colliding head-on, it is quite obvious that the normal reaction between the blocks would be impulsive in nature (and the normal force between the blocks and ground is ...
