Frictional forces stop us from slipping when we walk and slow down a cyclist when they stop pedalling.

momentum
p=m x v
p is the momentum in kilograms metres per second, kg m/s
m is the mass in kilograms, kg

velocity graphs
The velocity of an object is its speed in a particular direction. Two cars travelling at the same speed but in opposite directions have different velocities.
A velocity-time graph shows the speed and direction an object travels over a specific period of time. Velocity-time graphs are also called speed-time graphs.
The vertical axis of a velocity-time graph is the velocity of the object. The horizontal axis is the time from the start.
