- 1Gravitational potential energyEp = m g h
- 2Kinetic energyEk = 1
---- m v2 (squared)
2 - 3WeightW = m g
- 4WorkW = F s
- 5PowerP = E/t
OR
P = W/t - 6EfficiencyEfficiency = Useful energy
--------- x100
Total energy - 7ChargeQ = I t
- 8Elastic potential energyEe = half k e2 (squared)
- 9Potential Difference (Ohm's Law)V = IR
(Volts = Current x Total resistance) - 10PowerP = VI
- 11Power(I x I) x R
- 12Energy TransferE = Pt
- 13Energy TransferE = QV
- 14Densitymass
Density = ---------
Volume - 15Pressureforce normal to a surface
Pressure = -----------------------------------
area of that surface - 16Change in pressure or volumep1 x v1 = p2 x v2
- 17Accelerationchange in velocity / time taken
- 18Uniform motion w/ timeV = U + at
- 19Uniform motion w/o timeV(Sq) - U(Sq) = 2as
- 20MomentumP = mv
- 21Newtons 2nd lawF = ma
- 22Acceleration(v-u) / t
- 23Inertial massForce/acceleration
- 24Newtons 3rd LawF1 = F2
(when two objects interact the forces are equal and opposite) - 25Force in momentum changeF = m (v-u) / t
- 26MomentM = Fd
- 27Pressure due to a column of liquidp = height of column x density of liquid x gravitational field strength
- 28Force in a springF = ke
