Momentum and Impulse

Front

What is the standard metric unit of momentum?

Back

Kilograms * meter / second

Front

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

Back

Mass and velocity

Front

What is the formula for calculating impulse?

Back

Impulse = Change in momentum = Force * time

Front

If a 5 N force is applied to a 3 kg ball slowing it from 9 m/s to 3 m/s, what is the impulse?

Back

-18 N⋅s

Front

How do you calculate the momentum of an object?

Back

Momentum = mass * velocity

Front

What is the momentum of a biker with a mass of 75 kg moving at 5 m/s?

Back

375 kg m/s

Front

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

Back

Their velocities will decrease.

Front

What is the relationship between force and impulse?

Back

Impulse is equal to the change in momentum, which is also equal to the force applied multiplied by the time duration of the force.

Front

Define momentum in physics.

Back

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

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.
