Deceleration is a term used in physics and mathematics to describe the process of slowing down or reducing speed. It is the opposite of acceleration, meaning that something is moving at a decreasing rate or getting slower over time.
In mathematical terms, deceleration occurs when the rate of change of speed is negative. For example, if a car is moving fast and the driver starts to apply the brakes, the car undergoes deceleration because its speed is decreasing. Understanding deceleration is important in GCSE Maths as it helps students analyse and interpret motion in real-life situations.
