Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity ÷ time taken. is the rate of change of velocity. It ...

The speed of a body gives us an idea of how slow or fast that body is moving. For example if a car is running slow, we say that its speed is low. And if a car is running fast, then we say that its ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.
