A place or object used for comparison to determine if another object is in motion is called a

• comparison point
• reference point
• point of view
• motion detector

Velocity is

• speed and acceleration
• constant speed
• a frame of reference
• speed in a given direction

On a distance vs. time graph, the steeper the slope _____

• the slower the speed
• the faster the speed
• less acceleration
• greater acceleration
