Does the angle a ball hits the wall affect the angle it rebounds?
Bouncing at an angle. If the ball is incident to the wall at some angle, the rebound is at the same angle, provided the ball had no spin before or after the collision.
What type of collision is a rebound?
When a ball is dropped to the ground, one of four things may happen: It may rebound with exactly the same speed as the speed at which it hit the ground. This is an elastic collision.
Why do objects bounce when they hit the ground?
So, objects bounce because, when they hit each other, they can’t occupy the same space; they push each other apart. Those two outward forces, one on each object, one on the object hitting the floor, for example, and one on the floor, they push each other apart and that causes the bouncing effects.
What happens when an object hits a wall?
The wall doesn’t move, but the object moves in the opposite direction. Assume this is an ideal, elastic collision. I have a feeling this is wrong, so anybody clarify this for me? Yes, it is wrong. You are wrong if you think that in an ideal, elastic collision the velocity of the bouncing object is exactly the same.
What happens when the ball comes in contact with the wall?
When the ball comes in contact with the wall, there is a force exerted on the ball. Here is a diagram of the perfect collision. When dealing with forces and momentum, we should of course consider the Momentum Principle: In this special collision, the force from the wall is only perpendicular to the wall (in the y-direction).
When is momentum conserved when an object bounces back against a wall?
If, initially, the momentum of the system came from the ball, and after the collision, the momentum of the system was also from the ball, but in opposite directions, then momentum would not have been conserved? I have a feeling this is wrong, so anybody clarify this for me? Is momentum conserved when an object bounces back against a wall?
Is it wrong to think that the wall doesn’t move?
Yes, it is wrong. You are wrong if you think that in an ideal, elastic collision the velocity of the bouncing object is exactly the same. And also you are wrong if you think that the wall doesn’t move. You can’t see it move but it wouldn’t only if it had infinite mass, which is impossible.
