equations

• kinetic = 1/2$\times$mass$\times$velocity$^2$
• power = energy transferred$\div$time

  power=work done$\div$time
• shc equation:

  change in energy = mass x specific heat capacity x temperature change
• elastic potential energy =1/2$\times$spring constant$\times$extension$^2$
• gravitational potential energy=mass$\times$gravitational field strength$\times$height
• charge flow=current$\times$time
• potential difference=current$\times$resistance
• power=current$\times$potential difference
• power= current$^2$$\times$resistance
• power= energy$\div$time
• energy transferred = charge flow $\times$ potential diference
• force = spring constant $\times$ extention
• density = mass $\div$ volume
• energy required to change state = mass $\times$specific latent heat
• pressure $\times$ volume = constant
• radioactive decay formula = 1/2$^n$

  n = number of half lives
• net decline ratio = 1-radioactive decay formula
