| Question | Answer |
| Force acting on object in projectile motion | Gravity acting downwards (9.8ms^-2) |
| Projectile Motion Horizontal velocity and Vertical Velocity Laws | Vertical Velocity is 0 at top Horizontal velocity is constant |
| Direction of acceleration on object in circular motion | Towards centre of circle |
| Direction of velocity on object in circular motion | At tangent to the circle |
| Newtons Third Law | Every force has an equal and opposite reactant force |
| Newtons Second Law | Fnet = ma Unbalanced forces cause acceleration |
| Newtons First Law | If net force = 0 an object will not accelerate |
| Torque Definition | The turning affect of a force Force multiplied by perpendicular direction |
| Equilibrium Definition | An object has balanced forces and it therefor not accelerating Forces = 0 Clockwise Torque = Anticlockwise Torque |
| Conservation | Energy is conserved Momentum is conserved |
| Definition of Work | Energy transferred (If energy is conserved work = energy) |
| Elastic Collision | Kinetic energy is conserved |
| Inelastic Collision | Kinetic energy is not conserved |
| Electric Field Definition | Region where a charged object experiences a force (Positive to negative) |
| What does a charge in a electric field cause? | A force |
| Series Circuit Current, Voltage and Resistance | Current is constant Voltage adds up to supply voltage Resistance adds up |
| Parallel Circuit Current and Voltage | Current adds up to supply current Voltage is constant |
| Magnetic Field of straight wire | Right Hand Grip Current is thumb Magnetic Field is fingers |
| What a Current Carrying wire in a magnetic field causes | A Force |
| F = B q v | Right Hand Slap Current is Thumb Magnetic Field is fingers Force is Palm |
| Changing magnetic Field inside a coil causes | A Force |
| V = B v L | Right Hand Slap Velocity is thumb Magnetic Field is fingers Current is palm |
