Motion and Forces

Distance and direction of an object's change in position from a starting point

• displacement
• distance
• motion
• reference point

Vector quantities need both a magnitude and a _____.

• distance
• displacement
• direction
• velocity

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

Speed =

• distance / time
• time / distance
• distance * time

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

On a distance-versus-time graph, a straight line ALWAYS indicates that an object’s speed is _____.

• constant
• zero
• increasing
• decreasing

When something has speed in a certain direction it is called ___________.

• motion
