## Resource summary

Forces and Motion
1 Force and linear motion
1.1 Speed = distance travelled/ time taken
1.2 On distance-time graphs steeper the line the greater speed of the object
1.3 speed = distance/ time
1.4 Unbalanced forces can change the speed or direction of an object
1.5 Balanced forces will produce no change in the movement of an object
1.6 Forces such as air resistance, friction, weight and Gravity exist
2 Forces and Rotation
2.1 moment (turning effect) = force x distance (units Newton Metres)
2.2 Forces can cause an object to turn around on a pivot
3 Force and Presure
3.1 Pressure=force / area (units=N/cm2)
3.2 Pressure is exerted by solids, Liquids and gasses
4 Vocabulary: Turning effect of forces= moments
5 Calculating a moment: M= FxD
