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.
The relationship between acceleration, velocity change and the time taken for the change is given by this formula. \(\text{acceleration}=\frac{\text{change in velocity}}{\text{time taken}}=\frac{\text ...
