Efficiency=(Useful output/Total input) x 100 - for percentage 1 of 12 How would you calculate work done? Work done= Force x Distance moved 2 of 12 How would you work out the potential diference? Potential difference= Energy transferred/Charge 3 of 12 How would you calculate the resistance? Resistance= Voltage/Current 4 of 12 How would you calculate power? Power= Energy/Time 5 of 12 How would you calculate the power supplied? Power supplied= Current x Potential difference 6 of 12 How would you calculate the current? Current= Charge/ Time 7 of 12 How would you work out the voltage? Voltage= Power/ Charge 8 of 12 How would you work out the gravitational potential energy? Gravitational potential energy= mass x Gravitational field strength x height 9 of 12 How would you calculate kinetic energy? Kinetic energy= 1/2 x mass x Velocity 10 of 12 How would you calculate the velocity? Velocity= Kinetic energy/ 0.5 x mass 11 of 12 How would you work out the frequency? Frequency= 1/ Time period 12 of 12
