2.1 Acceleration and motion equations

IB Physics: 2.1 Acceleration and motion equations

Acceleration is defined as the rate of change of velocity:If the velocity of a body changes then it has acceleration, regardless of whether it is slowing down or speeding up. This differs from everyday language where acceleration means getting faster and deceleration is getting slower. If a moving body changes direction, its velocity changes. This means the body accelerates even if the speed is constant.
