AI Thread Summary
When a ball hits a wall, it exerts a force on the wall, and the wall exerts an equal and opposite force on the ball, illustrating Newton's third law. These forces do not cancel each other out because they act on different objects. The ball does not move with constant velocity after the impact because the net force acting on it is not zero; it experiences a change in momentum. Understanding that action and reaction forces act on separate bodies clarifies why the ball does not maintain its velocity. This principle is fundamental in analyzing collisions and motion in physics.

Homework Statement


A ball hits the wall.So wall will exert an equal and opposite force the ball
Why doesn't the ball's forces gets equal so it moves with constant velocity?

Welcome to PF :smile:
The ball exerts a force on the WALL and the wall exerts a force on the BALL.
So the forces are not acting on the same object to be cancelled.Newton's third law doesn't state that.
For every action,there is an equal and opposite reaction.That does not mean the forces act on the same object. :wink:

Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
