Question

1. Which of the following is/are the best example(s) of elastic collisio(s)?

A) A collision between two billiard balls.

B) A collision between two automobiles.

C) A basketball bouncing off the floor.

D) An egg colliding with a brick wall.

For this I am thinking the answer is A and C

2. In an elastic collision, What happens to the change in kinetic energy?

A) It is transformed into heat and also used to deform colliding objects.

B) It is converted into potential energy.

C) It is transformed into momentum such that momentum is conserved.

D) All of the above.

E) None of the above.

Not sure about this.

Explanation / Answer

1. A collision between two billiard balls is nearly elastic.So option (A) is correct.

2.In an elastic collision change in kinetic energy will be converted into elastic potential energy which again inturn converted into kinetic energy.So option (B) is correct.
