Speed, Velocity, Momentum Definitions Review

Front

What is the unit for velocity?

Back

Velocity can be measured in miles/hour, meters/second, cm/second, or km/hour. All of these are valid units for velocity.

Front

Two people moving at the same speed but who have 2 different weights have 2 different______?

Back

momentum

Front

What is the unit for momentum?

Back

Momentum is measured in Lbs x miles/hour.

Front

What does Newton's 2nd Law state?

Back

Force = Mass x Acceleration.

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time.

Front

Define speed.

Back

Speed is the distance traveled per unit of time.

Front

Define velocity.

Back

Velocity is the speed of an object in a specific direction.

Front

Define momentum.

Back

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

Front

What is the relationship between mass and momentum?

Back

Momentum increases with greater mass if velocity remains constant.

Front

What is the difference between speed and velocity?

Back

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