Physics, Motion in One Dimension Review

Which of the following is a scalar quantity?

• displacement
• force
• 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.

Does the speedometer in a car measure velocity or speed?

• velocity
• speed
• both
• neither

You and your dog go for a walk to the park.  On the way, your dog takes many side trips to chase squirrels or examine fire hydrants.  When you arrive at the park, do you and your dog have the same displacement?

• yes
• no
