Momentum

Front

What is the equation to calculate momentum?

Back

p = m x v

Front

How do you determine the momentum of an object?

Back

Multiply the mass (m) of the object by its velocity (v).

Front

What is the momentum of a 1000-kg car moving southward at 20 m/s?

Back

20000 kg*m/s south

Front

What must an object be doing in order to have momentum?

Back

Moving

Front

Which object has the most momentum if they are all rolling at the same velocity: a bowling ball, a tennis ball, or a marble?

Back

Rolling bowling ball

Front

What is the unit for momentum?

Back

kg*m/s

Front

If an object's mass doubles while its velocity remains constant, what happens to its momentum?

Back

The momentum doubles.

Front

If two objects have the same momentum, what can be said about their mass and velocity?

Back

Their mass and velocity are inversely related.

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

How does the direction of velocity affect momentum?

Back

Momentum has both magnitude and direction; it is a vector quantity.
