What is the equation that links speed, distance & time?
distance = speed/time
speed = distance/time
time = distance x speed
speed x distance = time

How could you calculate the speed of the car from any section in this graph?
Find the Colour of the section.
Find the area underneath the line for each section.
Find the gradient of the line in the section.
Combine all lines to make a pretty shape and work out the area inside it.
The image shows 3 identical triplets, all with the same mass and therefore weight.
The triple on the right of the seasaw has a weight of 500N and sits 2m away from the pivot in the centre.
How far away from the pivot point must the triplets on the left sit to balance the seasaw?
0.5m
4m
2m
1m
What is the formula for Moments about a pivot point?
Moment = Force X Perpendicular Distance
Moment = Force/ Perpendicular distance
Moment = Force
Moment = Perpendicular distance/ Force
