A location to which you can compare other locations is called

• reference point
• motion
• location
• position

The change of position over time is called

• position
• motion
• speed
• location

Speed is equal to the distance divided by

• position
• time
• height
• motion

Speed in a specific direction is called

• speed
• acceleration
• position
• velocity

Stating that a man is traveling north at 30 m/s is an statement of his

• speed
• velocity
• accleration
• endurance

If Bj is walking 3 m/s to the north and Lauren is walking 3 m/s to the west, then which of the following is true

• They have the same speed and different velocities
• They have the same velocity and different speeds
• They have the same speed and velocity
• They have different speeds and different velocities

A car goes from 0 m/s to 60 m/s in a period of 5 seconds find its acceleration.

• 10 m/s^2
• 12 m/s
• 12 m/s^2
• 11 m/s
