Question

which of the following units is used to measure acceleration? *
meters per second
kilometers per hour
meters per second, squared (m/s*2)
force

Explanation:

Acceleration is the rate of change of velocity. Velocity is displacement per time, and acceleration is change in velocity per time. So the unit is displacement per time squared. Meters per second squared ($m/s^{2}$) is the SI - unit for acceleration. Meters per second and kilometers per hour are units of velocity. Force has its own unit (Newton) and is not a unit for acceleration.

Answer:

C. Meters per second, squared ($m/s^{2}$)
