Deceleration, in the context of GCSE Physics, refers to the process of slowing down or reducing velocity. It is essentially negative acceleration, meaning the rate at which an object’s speed decreases over time. When an object decelerates, its velocity decreases, which is often due to opposing forces such as friction or air resistance.
Like acceleration, deceleration is measured in metres per second squared (m/s²). Understanding deceleration is crucial for analysing scenarios involving motion, where it is important to know how the speed of an object changes and the forces affecting this change.
