Both displacement and velocity are vector quantities.
Displacement is a distance in a particular direction.
Velocity is speed in a given direction.
The average velocity is given by:
This can be written as:
Displacement can be negative or positive as it is a vector quantity
The gradient of a displacement time graph gives the velocity.
Velocity can be negative or positive as it is a vector quantity.
When the gradient is zero, the velocity is zero and the object is stationary.
At A, the gradient is zero, so the velocity is zero and the object is stationary.
A negative gradient means the object is travelling in the opposite direction.
At B the gradient is negative so the object has reversed direction.
