Determine the magnitude of the acceleration for both phases, speeding up and slowing down.

♦ Relevant knowledge

Acceleration is, by definition, a quantity that describes the change in velocity with time. This is the fundamental quantity used to describe motion. Acceleration, like velocity, is a directional quantity. The dimension of acceleration is length per square of the time.

A constant velocity does not mean that an object is accelerating. Acceleration is only possible when the velocity changes. If the velocity changes at a constant rate, then the object will move with constant acceleration. The SI system of units uses m/s2 to indicate acceleration.

Motion accelerates when it is in the same direction, decelerates when it is opposite, and changes direction when its acceleration vector differs from the direction.

Acceleration = Δv/Δt
