1.3 Velocity
1.3.1 Speed in given direction
1.4 Acceleration
1.4.1 Change of velocity
1.4.2 a = (v-u)/t
2 Forces
2.1 Two objects
2.1.1 Always exert equal and opposite forces
2.2 Resultant force
2.2.1 Zero Stays at rest of object is at rest Carry on moving at same speed if object is moving
2.2.2 Causes acceleration Bigger the force, greater the acceleration
2.3 On the road
2.3.1 Stopping distance BD + TD
2.3.2 Thinking distance Driver Tired Alcohol Drugs

2.4 Falling objects
2.4.1 Fluid Exerts a drag force Terminal velocity Velocity it reaches when it falls
2.5 Stretching and squashing
2.5.1 Extension Difference between the length of spring and its original length
2.5.2 Extension directly proportional
2.5.3 Stiffer spring Greater spring constant
2.5.4 Elastic potential energy stored When work is done
3 Energy and Momentum
3.1 Gravitational potential
3.1.1 Stored Position in Earth's gravitational field.
3.2 Kinetic
3.2.1 Greater mass Faster speed
3.3 Momentum
3.3.1 Greater mass and velocity
3.4 Two objects push each other
3.4.1 They move apart with different speeds Equal and opposite momentum
4 Current Electricity
4.1 Electrical charges
4.1.1 Insulating materials Charge when rubbed
4.2 Resistance
4.2.1 Potential difference / current

4.3 Current-potential graphs
4.3.1 Filament bulb Curve
4.3.2 Diode Forward resistance low
4.3.3 Thermistor Resistance decreases if temp increases
4.4 Series circuit
4.4.1 Connected one after other
4.4.2 Current same
4.5 Parallel circuit
4.5.1 Total current = all currents Bigger resistance, smaller current I = (V / R)
