Momentum and Impulse Review - AP Physics 1

Front

What is momentum?

Back

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

Front

What is impulse?

Back

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

Front

What is the principle of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.

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

How does gravity affect falling objects?

Back

Gravity is an external force that acts on falling objects, causing them to accelerate downwards.

Front

What happens to the center of mass of a system when external forces are absent?

Back

The velocity of the center of mass remains constant if no external forces act on the system.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object, expressed as Impulse = Δp.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v).

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.
