Momentum and Impulse

Front

What is momentum?

Back

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

Front

How is impulse defined?

Back

Impulse is defined as the change in momentum of an object when a force is applied over a period of time, represented by the formula Impulse = Force × Time.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object.

Front

What is an elastic collision?

Back

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

Front

What is an inelastic collision?

Back

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

Front

What is the formula for calculating momentum?

Back

The formula for calculating momentum is p = mv, where p is momentum, m is mass, and v is velocity.

Front

What factors affect the momentum of an object?

Back

The momentum of an object depends on its mass and velocity.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before and after a collision remains constant.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved; in inelastic collisions, only momentum is conserved.

Front

What happens to momentum in a perfectly inelastic collision?

Back

In a perfectly inelastic collision, the colliding objects stick together, and the total momentum is conserved, but kinetic energy is not.
