Velocity and acceleration.

Velocity and acceleration are both different to speed:
Velocity is the speed at which something is moving in a certain direction.
And acceleration is how quickly the velocity is changing- this could be a change in speed or in
direction

To work out acceleration:

Acceleration= change in…

Now you know the features you also need to know how to calculate acceleration, velocity and
distance using a velocity time-graph.

To work out the acceleration on a distance time graph you must use the equation-
Acceleration= gradient= vertical change/ horizontal change.
Example: Using this velocity time graph find out…
