Short explanation

Acceleration is defined as the rate of change of velocity, indicating how quickly an object speeds up, slows down, or changes direction. It is measured in metres per second squared (m/s²), which reflects the change in velocity (in m/s) that occurs each second. For example, if a car increases its speed from 10 m/s to 20 m/s in 5 seconds, its acceleration can be calculated as the change in velocity divided by the time taken. Understanding acceleration is crucial in analyzing motion and the effects of forces acting on objects.

Misunderstanding Acceleration Units: Remember that acceleration is the rate of change of velocity, which requires the time component to be squared in the units. Always express acceleration as m/s².
