Momentum and Impulse

Front

What happens to the momentum of an object when its speed is doubled?

Back

The momentum doubles.

Front

What two factors does the momentum of an object depend on?

Back

Mass and velocity.

Front

What occurs to the velocities of two objects that collide and stick together?

Back

Their velocities will decrease.

Front

Calculate the momentum of a 0.250 kg cart moving at 0.400 m/s.

Back

0.1 kg-m/s.

Front

What are the standard metric units of momentum?

Back

Kilograms * meter / second.

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

If an object's mass is halved while its speed remains constant, what happens to its momentum?

Back

The momentum is halved.

Front

In a closed system, what is conserved during a collision?

Back

Momentum is conserved.

Front

What is impulse?

Back

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