Resource summary

Motion and forces
1 Speed
1.1 No direction specified
1.2 How fast you are going
1.3 Speed=distance/time
2 Velocity
2.1 Direction specified
2.2 How fast you are going
3 Acceleration
3.1 How quickly velocity is changing
3.2 Vector quantity
3.2.1 Magnitude
3.2.2 Direction
3.3 Acceleration=change in velocity/time taken
4 Distance time graphs
4.1 Gradient=speed
4.2 Flat sections=stopped
4.3 Curves=acceleration
5 Velocity time graphs
5.1 Gradient=acceleration
5.2 Flat sections=steady speed
5.3 Curve=changing acceleration
6 Forces
6.1 Size or arrow relates to size of force
6.2 Gravity is a force
6.2.1 This causes a reaction force of the surface of the earth
6.3 With no reaction force an object would accelerate
6.4 Acceleration is unbalanced forces
6.5 The bigger the unbalanced force, the greater the acceleration
6.6 Action force
6.7 Reaction force
6.8 Resultant force
7 Weight and mass
7.1 They are not the same
7.2 Weight is a force
7.2.1 Measured in newtons
7.2.2 Caused by gravity
7.3 Mass is not a force
7.3.1 Measured in kg
7.3.2 Amount of 'stuff' in an object
7.4 Weight=mass x gravitational field strength
8 Objects in a vacuum
8.1 Accelerate at the same speed
8.2 Remember the hammer and the feather on the moon
8.2.1 They both land at the same time
8.3 Objects in an atmosphere
8.3.1 Terminal velocity
8.4 No terminal velocity
