The SI unit for length or distance is

• foot (ft)
• inch (in)
• mile (mi)
• meter (m)

A change in velocity over time is known as:

• acceleration
• constant speed
• average speed
• displacement

How do you calculate average speed?

• divide total time by total distance
• multiply total time by total distance
• divide total distance by total time
• subtract total time from total distance

An object starts its linear motion from rest. Which of the following quantities does not change throughout the motion?
