Question

multiple - choice question
what are the units for acceleration?
□ m/s²
□ km/hr²
□ km/hr
□ m/s

Explanation:

Acceleration is the rate of change of velocity. Velocity has units of length per time (e.g., m/s or km/hr), and acceleration is change in velocity per unit time. So its units are length per time - squared. In SI units, it's m/s². But km/hr² is also a valid unit for acceleration in non - SI contexts for larger distances. km/hr is a unit of velocity and m/s is also a unit of velocity.

Answer:

A. m/s², B. km/hr²
