Front

The equation to calculate momentum is

Back

Front

In order for an object to have momentum it must be ________

Back

moving

Front

Which of the following has the MOST momentum? (they are all rolling at the same velocity) rolling ping-pong ball, rolling bowling ball, rolling soccer ball, rolling basketball

Back

rolling bowling ball

Front

If an object has a momentum of 40 kg x m/s and a mass of 60 kg, what is its velocity?

Back

.67 m/s

Front

Define momentum in physics.

Back

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

Front

What is the formula for calculating momentum?

Back

p = m x v, where p is momentum, m is mass, and v is velocity.

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum if moving at the same velocity.

Front

How does velocity affect momentum?

Back

The greater the velocity of an object, the greater its momentum if mass remains constant.

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.
