SPEED = Distance/Time
DISTANCE = Speed X Time
TIME =Distance/Speed
E.g
If Sarah drives at an average speed of 100km/h and it takes her 2 hours to complete her journey.
What was the full distance of her journey?
ANS = 100km/h x 2
200km
Velocity= the speed of an object in a given direction
velocity is measured in m/s2
Acceleration= an increasing speed of an object
acceleration measured in m/s

Distance time graphs
When labelling the y and x axis, remember that the x axis always has to be a constant number. In this case, time is the constant. When the graph is steep, it shows that more distance is being travelled over a shorter period of time meaning that the speed has increased/decreased tremendously.
Velocity time graphs
Velocity time graphs
A steep line shows a more rapid change in the velocity of the object. A steep line going up shows acceleration. A flat line shows a constant velocity and a line sloping downwards shows deceleration.
