Review Flashcard Momentum

Front

What is the unit of momentum?

Back

kgm/s

Front

What does momentum describe?

Back

Momentum is a quantity that describes the mass and velocity of an object in motion.

Front

How is momentum affected in a collision if two objects are moving at the same speed?

Back

If they are going the same speed before the collision, they will lose the same momentum.

Front

True or False: The total momentum of a closed system remains constant before and after an event.

Back

True

Front

Which has more momentum: a giant semi truck at rest or a toddler on a scooter?

Back

A toddler on a scooter has more momentum.

Front

What is the formula for calculating momentum?

Back

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

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What happens to momentum in an elastic collision?

Back

In an elastic collision, both momentum and kinetic energy are conserved.

Front

What happens to momentum in an inelastic collision?

Back

In an inelastic collision, momentum is conserved, but kinetic energy is not.

Front

What is the relationship between force and momentum?

Back

Force is the rate of change of momentum over time (F = Δp/Δt).
