Collisions

Front

What subtopic of conservation of momentum deals with different types of collisions, such as elastic and inelastic collisions?

Back

Collision Mechanics

Front

In an elastic collision, what happens to the total kinetic energy of the system?

Back

It is conserved.

Front

Which type of collision involves objects bouncing off each other and conserving both momentum and kinetic energy?

Back

Perfectly elastic bounce collision.

Front

What is the law that states that the total momentum of a closed system remains constant before and after a collision?

Back

Law of conservation of momentum.

Front

Define momentum in the context of physics.

Back

Momentum is the product of an object's mass and its velocity, represented as p = mv.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved; in inelastic collisions, momentum is conserved but kinetic energy is not.

Front

What is an example of a perfectly elastic collision?

Back

Collisions between gas molecules are often considered perfectly elastic.

Front

What is an example of an inelastic collision?

Back

A car crash where the vehicles crumple together is an example of an inelastic collision.

Front

What is impulse in relation to momentum?

Back

Impulse is the change in momentum resulting from a force applied over a period of time, calculated as Impulse = Force × Time.
