Momentum, Impulse, and Conservation of Momentum

Front

What is the symbol for impulse, with units?

Back

J, N s

Front

The Law of Conservation of Momentum states:

Back

The total momentum before a collision is equal to the total momentum after a collision.

Front

Which takes more force to catch, a bowling ball or a ping pong ball?

Back

Bowling ball because it has more momentum.

Front

Which one of the following units represents the standard metric units of impulse?

Back

Newton * second

Front

A 5 N force is applied to a 3 kg ball to slow it down from 9 m/s to 3 m/s. What is the impulse on the ball?

Back

-18 N⋅s

Front

Define momentum.

Back

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

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg m/s).

Front

Explain impulse in terms of momentum.

Back

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

Front

What is the formula for impulse?

Back

Impulse (J) = Force (F) × Time (t) or J = Δp (change in momentum).

Front

How does mass affect momentum?

Back

An increase in mass results in an increase in momentum if velocity remains constant.
