Question

Which situations describe an elastic collision?

1.Two glass marbles bounce off each other.
2.Rodrick flops onto his sofa and sinks into the cushion.
3.A tossed water balloon flattens when it lands on the grass.
4.A bowling ball knocks over five pins.

It can be more then one answer which are the correct Please help!

Answer 1

Elastic collisions are collisions in which both momentum and kinetic energy are conserved. I think the correct answer from the choices listed above is option A. Two glass marbles bounce off each other is an example of an elastic collision. Hope this answers the question.

Answer 2

Answer:

Option (1)

Explanation:

There are two types of collision.

1. Elastic collisions

2. Inelastic collisions

The conditions for elastic collisions are given below:

a. the momentum is conserved.

b. kinetic energy is conserved.

c. all the forces during the collision are conservative in nature.

The conditions for inelastic collisions are given below:

a. the momentum is conserved.

b. the mechanical energy is conserved.

c. all or some of the forces are non conservative in nature.

When the two glass marbles strikes and bounce off each other, the momentum and kinetic energy both are conserved so it is the example of elastic collision.
