Physics Equations

• work done = force x displacement
• energy = power x time
• power = current x voltage
• voltage = current x resistance
• power (no voltage) = current^2 x resistance
• charge = current x time
• energy (charge) = charge x voltage
• force = mass x acceleration
• efficiency = useful energy output/total energy input (x100)
• density = mass/volume
• speed = distance/time
• pressure = mass/area
• kinetic energy = 0.5 x mass x speed^2
• gravitational potential energy = mass x gravitational field strength x height
• resistance = potential difference/current
• acceleration = change in velocity/time
