BRAINCAKEDisplacement and Velocity
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.
