Physics equations

• potential difference= current x resistance
• GPE= gravitational field strength x mass x height
• KE= 0.5 x mass x velocity^2
• power= work done/time taken or energy transfered/time taken
• efficiency= useful energy/ total energy
• elastic potential energy= 0.5 x spring constant x extension^2
• change in thermal energy = mass x specific heat capacity x change in temperature
• charge flow = current x time
• total resistance = resistance of 1 + resistance of 2
• power = current x potential difference
• power = current^2 x resistance
• energy transferred =power x time
• energy transferred = charge flow x potential difference
• density = mass/ volume
• change in thermal energy = mass x specific heat capacity x change in temperature
• thermal energy for a change in state = mass x latent heat of fusion/vaporization x temperature change
• constant = pressure x volume
• force = mass x acceleration
