- Resultant Force
- P2
- Distance Time graphs
- Gradient = Rise /Run (change in y/ change in x)

- Acceleration
- A = (v-u)/t
- A= Acceleration (ms-2) V= Final velocity (Ms-1) U= Initial velocity (ms-1) t= Time taken (s)

- A = (v-u)/t
- Rate of Change of Velocity
- Work done and Power
- WD = F x D
- Power is the rate of use of energy ... 1 Watt is 1 Joules per second

- Distance Time graphs
- Overall net force acting on an object (Difference between the forces.
- If the Resultant force is 0 the object could be : Not moving, Traveling at a constant speed.
- If the resultant force is not 0 the object will accelerate

- P2
- Weight and Mass
- Mass is how heavy something is. It is measured in KG
- P2
- Distance Time graphs
- Gradient = Rise /Run (change in y/ change in x)

- Acceleration
- A = (v-u)/t
- A= Acceleration (ms-2) V= Final velocity (Ms-1) U= Initial velocity (ms-1) t= Time taken (s)

- Rate of Change of Velocity
- Work done and Power
- WD = F x D
- Power is the rate of use of energy ... 1 Watt is 1 Joules per second

- Distance Time graphs
- Weight is the force on an object due to gravity. It is measured in Newtons.
- W Weight = N M Mass = KG g gravitational field strength = 9.81ms-2

- Terminal Velocity
- In the absence of air (and therefore air resistance) All objects accelerate at the same rate, regardless of the mass.
