How do you work out average speed?
Total journey Distance/total journey time
What is Instantaneous speed?
How fast you are going at that moment
What is Acceleration?
Tells you how quickly your velocity is changing.
How do you calculate acceleration (m/s2)?
Change in velocity(m/s)/time(s)
On a graph what does the line do when the object is stationary?

On a graph what does the line do when the object is moving at a constant speed?
Is a straight line that slopes up
What is deceleration?
The change of velocity per second when an object slows down
