Throwing a ball on smooth surface.

[Physicsissuef]

What is the direction of beating off some rubber ball, throwed on some smooth surface? It depends of the angle that I will throw the ball and why?

Does this article on the conservation of linear momentum in collisions help?

I would like to clarify that the term "beating off" is not scientifically accurate in this context. The correct term would be "bouncing" or "rebounding".

The direction of the ball's rebound on a smooth surface would depend on several factors, such as the angle at which it was thrown, the force applied, and the surface's texture and angle of inclination.

If the ball is thrown at a low angle, it will likely rebound in a similar direction, but with a lower velocity. If it is thrown at a high angle, it may rebound in a different direction due to the change in momentum.

The force applied to the ball also plays a role in its rebound direction. The greater the force, the higher the velocity of the rebound.

Additionally, the texture and angle of inclination of the surface can affect the ball's rebound. A smoother surface may result in a more predictable and consistent rebound, while a rough surface may cause the ball to bounce in unexpected directions.

In conclusion, the direction of a ball's rebound on a smooth surface is dependent on various factors and cannot be determined without specific information about the angle and force of the throw, as well as the properties of the surface.
