Question | Answer |
Weight | W=mg Weight= Mass x gravitational field strength |
Work Done | W=Fs Work done= Force x distance |
Kinetic Energy | 0.5 x Mass x Velocity^2 |
Gravitational Potential Energy | Ep= mgh Mass x gravitational field strength x height |
Specific Heat Capacity | energy transferred x specific heat capacity x change in temperature |
Resistance | Resistance = Potential Difference/Current |
Potential Difference | V= IR Potential Difference x Current x Resistance |
