• velocity
• speed

The slope of a two-dimensional position-time graph gives

• displacement.
• distance.
• velocity.
• acceleration.

Displacement must always be measured from

• the y-axis.
• a reference point.
• infinity
• the current position of an object.

On a position-time graph, the average velocity between two points is

• computed by change in position divided by change in time between the two positions.
• computed by change in time divided by change in position between the two positions.
• the horizontal displacement on the graph between the two positions.
• the vertical displacement on the graph between the two positions.

Which of the following is not a vector quantity?

• acceleration
• displacement
• velocity
• speed

The speedometer on your car measures

• average speed.
• average velocity
• instantaneous speed.
• instantaneous velocity.

Which one of the choices does not give you displacement, velocity, or acceleration

• area under a velocity-time graph
• slope of a velocity-time graph
• slope of a position-time graph
• area under a position-time graph

Which change results in zero acceleration of a system?

• d. a change in only the time interval in which direction and velocity are measured    
• a change in only the direction of velocity
• a change in only the magnitude of velocity
• a change in both the magnitude and direction of velocity
