Velocity and Momentum

Front

Total distance divided by total time is

Back

average speed

Front

_____ is how fast an object moves in a specific direction.

Back

velocity

Front

10 miles per hour is an example of an object's what?

Back

Speed

Front

What is the unit for momentum?

Back

kg x m/sec

Front

How can a tennis ball and a bowling ball have the same momentum?

Back

have different speeds

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / Time

Front

What is the difference between speed and velocity?

Back

Speed is scalar (magnitude only), while velocity is vector (magnitude and direction).

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

What are the units of momentum?

Back

The units of momentum are kg x m/sec.

Front

If an object is moving with constant speed, what can be said about its velocity?

Back

If the direction is constant, velocity is also constant; if direction changes, velocity changes.
