| Question | Answer | 
| Force | Force=mass x acceleration F=ma | 
| Density | Density= mass÷volume ρ=m÷v | 
| Speed | Average speed= distance÷time | 
| Acceleration | Acceleration= change in velocity÷time A= (v-u)÷t | 
| Weight | Weight= mass x gravity w= mg | 
| Moment around a point | Moment= force x distance from point m= fd | 
| Spring | Load= spring constant x extension F= kx | 
| Pressure | Pressure= force÷area P= f÷a | 
| Pressure (liquid) | Pressure= density x gravity x depth P=ρgd | 
| Temperature (Kelvin) | Temperature Kelvin= Temperature Celcius + 273 | 
| Gases | Pressure (1) x Volume (1)÷ Temperature (1)= Pressure (2) x Volume (2)÷ Temperature (2) | 
| Work | Work = Force x distance moved w= fd | 
| Work | Work = Force x distance moved w= fd | 
| Gravitational potential | GP= mass x gravity x height GP= mgh | 
| Kinetic energy | KE= half x mass x velocity^2 KE= 1/2mv^2 | 
| Specific heat capacity | Energy transferred= mass x specific heat capacity x temp change E= mcΔt | 
| Latent heat | Energy transfered= mass x latent heat E= mL | 
| Power | Power= work ÷ time= energy transferred ÷ time p= w÷t | 
| Efficiency | Efficiency= work done ÷ input= energy output ÷ input= power output ÷ input | 
| Wavespeed | Speed= frequency x wavelength v= fλ | 
| Period | Frequency= 1 ÷ period f= 1÷t | 
| Refraction | Refractive index= sin angle of incidence÷ sin angle of reflection n= sin(i)÷sin(r) | 
| Internal reflection | Sin critical angle= 1÷reflective index sin c= 1÷n |
