What are some examples of an elastic collision?

Answer 1

Nathan Ashcroft

When we throw a ball on the floor, it bounces back. This is an example of elastic collision where both momentum and kinetic energy are conserved.
The collision between the atoms is also an example of elastic collision.
The collision between two billiard balls is an example of elastic collision.

Sure! Here are some examples of elastic collisions:

Two billiard balls colliding on a frictionless table.
Collisions between gas molecules in ideal gas conditions.
Collisions between atoms or subatomic particles in particle accelerators.
Collisions between stars in a galaxy, where they interact but do not merge due to the conservation of momentum and energy.

Nathan Ashcroft

Some examples of elastic collisions include:

Two billiard balls colliding on a pool table and then moving away from each other without losing kinetic energy.
Two air molecules colliding in a gas and then rebounding off each other without any loss of kinetic energy.
Two idealized springs with masses at either end colliding and then rebounding without any loss of kinetic energy.
Two cars colliding on an ice rink and then bouncing off each other without any loss of kinetic energy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
