The actual speed of a moving object at an exact moment is

• instantaneous speed.

• average speed.

Constant speed means the speed

• changes

• is a variable

• stays the same

Acceleration is the way we describe the changes in

• distance

• velocity

• time

Usain Bolt holds the world record for the fastest runner at 12.27 m/s. This is an example of

• acceleration

• speed

• velocity
