average speed
When an object moves in a straight line at a steady speed you can calculate its average speed if you know how far it travels and how long it takes The following equation shows the relationship between average speed distance moved and time taken
1 of 5
Falling objects
the forces affecting a falling object at different stages of its fall Usually you need to think about two forces
2 of 5
Power how is it measured
Power is a measure of how quickly work is being done and so how quickly energy is being transferred here is the equation that relates power work done and time
3 of 5
kinetic theroy
The kinetic theory describes a gas as a large number of submicroscopic particles atoms or molecules all of which are in constant rapid motion
4 of 5
Newtons law
Newton's First Law of Motion I Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it
