Is momentum conserved when a ball hits another ball?

A collision is a concept that describes what happens when two objects strike each other. No matter what type of collision you have, momentum will be conserved. This means that the total momentum of all of the colliding objects before the collision will be the same as the total momentum afterwards.

Does a ball have angular momentum?

7 Answers. Yes, it does. It may seem a bit more intuitive if you imagine a line connecting your reference point and the centre of the ball: as the ball moves, the line sweeps out an angle across the ball, so there should be some angular momentum.

How is momentum conserved when a ball is dropped?

When a body drops from a height, it gains momentum down, while the earth gains the same momentum up. Since the earth is very massive, you can not observe its motion in reaction. Same goes for a ball rolling downhill. Thus the net change in momentum is zero and the law of conservation of momentum is validated.

What is the direction of angular momentum of the ball?

perpendicular
angular momentum: A vector quantity describing an object in circular motion; its magnitude is equal to the momentum of the particle, and the direction is perpendicular to the plane of its circular motion.

What happens when two balls collide?

Two balls with equal masses, m, and equal speed, v, engage in a head on elastic collision. Since the balls of equal mass are moving at equal and opposite speeds, the total linear momentum of the system is zero. For linear momentum to be conserved after the collision, both balls must rebound with the same velocity.

How momentum is conserved when a ball bounces against a floor?

Explain how momentum is conserved when a ball bounces against a floor. It is conserved when there are no outside forced present and it has an equal and opposite traction. Also, the ball’s momentum is transferred to the ground. As a ball falls toward Earth, the momentum of the ball increases.

Why is angular momentum a thing?

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity—the total angular momentum of a closed system remains constant.
