Motion Unit Review

What are the two axis labels for an acceleration graph?

• speed and time

• time and distance

• left and right

• speed and distance

Motion is defined as...

• being in one place and then being in another.

• skipping happily.

• a change in position using a reference point.

• a physics term only physicists need to know.

Rate is a ______________ between two measurements.

• change

• ratio

• treaty

• conversation

The best definition for speed is

• how fast something moves

• how zippy my dog runs

• kachow

• instantaneous speed

• speed of many tiny moments averaged together

Speed that does not vary is called

• boring

• instantaneous speed

• variable speed

• constant speed

To calculate average speed you need to have which of the following information?

• A and B

• A and C

What is the equation for calculating speed?
