Momentum and Impulse

Front

What is an inelastic collision?

Back

A collision where objects collide and stick together, resulting in a loss of kinetic energy.

Front

What is the total momentum after a collision if a car with 10,800 kg m/s collides with a dumpster at rest?

Back

The total momentum will be the same: 10,800 kg m/s.

Front

Which has more momentum: a car at rest or a bike moving at 15 mph?

Back

The bike has more momentum.

Front

What type of quantity is momentum?

Back

Momentum is a vector quantity.

Front

What does the Law of Conservation of Momentum state?

Back

Momentum before a collision equals momentum after a collision.

Front

Define momentum.

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the formula for calculating momentum?

Back

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

Front

What happens to momentum in a closed system during a collision?

Back

The total momentum remains constant.

Front

What is an elastic collision?

Back

A collision where objects collide and bounce off each other, conserving both momentum and kinetic energy.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time.
