Equations Flashcards
Weight
Weight = mass x gravitational strength
Work done
Work done = force x distance
Force applied to spring
Force applied to spring = spring constant x extension
Distance travelled
Distance travelled = speed x time
Acceleration
Accelaration = change in velocity/time taken
Resultant Force
Resultant Force = Mass x accelaration
Momentum
Momentum = Mass x Velocity
Kinetic Energy
Kinetic Energy = 0.5 x Mass x Speed^2
Gravitational Potential Energy
Gravitational Potential Energy = Mass x gravitational field strength x height
Power
Power = Energy Transferred/time
Power
Power = Work done/time
Effiency
Effiency = Useful output energy transfer/total input energy transfer
Effiency
Effiency = Useful power output/total power output
Wave Speed
Wave speed = frequency x wave length
Charge flow
Charge flow = current x time
Potential difference
Potential difference = current x resistance
Power
Power = potential difference x current
Power
Power = current^2 x resistance
Energy Transferred
Energy Transferred = power x time
Energy Transferred
Energy Transferred = charge flow x potential difference
Density
Density = mass/volume
