- forces
- moment of a force = force x distance
- m=fd
- levers
- used to increase the force applied to an object
- gears
- gears are used to transmit rational forces from one place to another
- speeds
- walking - 1.5 m/s
- running - 3 m/s
- cycling - 6 m/s
- running - 3 m/s
- average speed = total distance travelled / time taken
- walking - 1.5 m/s
- distance travelled = speed x time
- s = vt
- displacement = how far an object has travelled in a straight line from the starting to finishing point
- moment of a force = force x distance
