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
Charge Flow Q= It Charge Flow= Current x time
Efficiency E= Et Useful energy/Total Energy
Weight Unit Newtons
Energy Unit Joules
Mass Unit Kilograms
Current Unit Amps
Charge Flow Unit Coulombs
Energy Transferred E=QV Coulombs x potential difference
Potential Difference Unit Volts
Latent Heat E= mL
Half-Life How long it takes for an atom to lose half of its mass
Internal Energy Kinetic Energy + Potential Energy
