What is momentum?

Back

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

When is momentum conserved?

Back

Momentum is conserved in all types of collisions, including elastic, inelastic, and perfectly inelastic collisions.

What happens to kinetic energy in an elastic collision?

Back

In an elastic collision, kinetic energy is conserved; the total kinetic energy before and after the collision remains the same.

Front

What happens to kinetic energy in an inelastic collision?

Back

In an inelastic collision, kinetic energy is partially lost to other forms of energy, such as heat or sound.

Front

Define elastic collision.

Back

An elastic collision is a type of collision where both momentum and kinetic energy are conserved.

Front

Define inelastic collision.

Back

An inelastic collision is a type of collision where momentum is conserved, but kinetic energy is not.

Front

What is a perfectly inelastic collision?

Back

A perfectly inelastic collision is a type of collision where the two colliding objects stick together after the collision, resulting in maximum kinetic energy loss.

Front

What is the difference between elastic and inelastic collisions?

Back

The main difference is that elastic collisions conserve both momentum and kinetic energy, while inelastic collisions conserve momentum but not kinetic energy.

Front

Can energy be created during a collision?

Back

No, energy cannot be created during a collision; it can only be transferred or transformed.

Front

What is the law of conservation of momentum?

Back

The law of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it.
