Torbid bats and sweet spot physics

If the ball reaches the stick and wears, what will happen to the stick? If you say that the stick will retreat to the right, then you are right. We can think about this as a collision. When she collides, they exercise forces on each other. For Newton, the forces are equal and opposite, while maintaining its total momentum of a system that has become a fixed ball. We define momentum as a product of the object and the speed of the object.

Since the ball rose, the only way to keep the momentum is for the stick with the apostasy. (I know, my preparation for this thought experience would make a sport of spectators, but stay with me – will help us understand what is happening in the sweet place).

Clash outside the center

Well, go to the stick and return it to the starting position. The ball was launched again towards the stick. However, this time, it aims to end instead of the middle. Likewise:

The stick is still retreating to the right, but now Spin About its center, right? Why does this happen? Well, the momentum is still preserved, but there is now another quantity reserved – compressed momentum. The angular momentum is very similar to the ancient ancient momentum except that it deals with rotational movement rather than linear movement.

While the linear momentum depends on the mass and speed of the object, the angular momentum equals the corner speed of the object and the moment of inertia. The moment of stagnation is like a circulatory mass – it depends on the mass of the object, but this mass is distributed. Therefore, after the stick retracts the effect of the ball, it is clear that it has an angle momentum, because it rotates.

But what about collision? The stick does not rotate and does not contain angular momentum, so in order to maintain angular momentum and then ball The momentum should be angular. Yes, the mass can have an angular momentum even if it does not rotate. (This is one of those moments when physics looks strange.) The angular momentum of the ball depends on its linear momentum and Where it hits the stick.
