| Question | Answer |
| Equation for average speed | average speed= distance moved/ time taken |
| Equation for force | Force = mass x acceleration |
| Acceleration= | acceleration= change in velocity/ time taken |
| Momentum = ? | Momentum = mass x velocity |
| Density = ? | Density = mass / volume |
| Work done = ? | Work done = force x distance moved |
| Work done = ? | Energy transferred = work done |
| Kinetic energy = ? | kinetic energy = 1/2 x mass x speed2 |
| GPE | GPE = mass x g x height |
| Weight = ? | Weight= mass x gravitational field strength |
| Pressure= ? | Pressure = force/ area |
| The relationship between movement of a force and it's distance from the pivot | movement = force x perpendicular distance from the pivot |
| charge = ? | charge = current × time |
| Voltage = ? | Voltage = current x resistance |
| electrical power= ? | electrical power = voltage × current |
| wave speed = ? | wave speed = frequency × wavelength |
| Relationship between voltage and turns | input (primary) voltage / output(secondary)voltage = primary turns / secondary turns |
| Refractive index = ? | n= sin i / sin r angle of incidence / refraction |
| Relationship between refractive index and critical angle | sin c = 1 / n |
| Efficiency = ? | efficiency = useful energy output / total energy output |
| Pressure difference | pressure difference = height × density × g p=h×ρ×g |
| Input power = ? | input power = output power Vp Ip = Vs Is for 100% efficiency |
