Here are all the equations you will need for GCSE:

- pressure = force/area
- density = mass/volume
- kinetic energy = 1/2 * mass * velocity
^{2} - refractive index = sin i/ sin r = speed of light in a vacuum/ speed of light in material
- Charge = Current * Tim
- Weight = Mass/g
- Gravitational Potential Energy = mass * height * g
- Power= Energy/ Time
- Power = Voltage * current
- Work Done = Force * Distance
- Acceleration = Change in velocity/Time
- Total resistance = R
_{1}+ R_{2}+R_{3}....(series circuit) = R_{1}R_{2}/(R_{1}+R_{2}) [parallel circuit] - Pressure*Volume/Temperature = constant
- Moment = Force * Distance
- Sin critical angle = 1/refractive index
- Force = k * extension
- Velocity = Frequency * Wavelength
- Pressure due to liquid = height * g * density
- Voltage = Energy/Charge
- Force = Mass * Acceleration
- Voltage = Current * Resistance
- V
_{p}/V_{s}= N_{p}/N_{s} - V
_{s}* L_{s</sub = Vp * Lp } _{Energy = mass * specific heat capacity * change in temperature }_{Energy = mass * latent heat of fusion(or vaporization)}
