Kinetic Energy =
0.5 x mass x (speed)²
Ek = ½ x m x v²
Elastic Potential Energy =
0.5 x spring constant x (extension)²
Ee = ½ x k x e²
Gravitational Potential Energy =
mass x gravitational field strength x height
Ep = m x g x h
Work Done =
force x distance
W = F x s
Power =
energy transferred / time
P = E / t
Power =
work done / time
P = W / t
Efficiency =
useful output energy transfer / total input energy transfer
Efficiency =
useful power output / total power input
Charge Flow =
current x time
Q = I x t
Potential Difference =
current x resistance
V = I x R
Power =
current² x resistance
P = I² x R
Energy Transferred =
power x time
E = P x t
Energy Transferred =
charge flow x potential difference
E = Q x V
Density =
mass / volume
p = m / V
Change in Thermal Energy =
mass x specific heat capacity x temperature change
Thermal Energy for a Change of State =
mass x specific latent heat
E = m x L
Weight =
mass x gravitational field strength
W = m x g
Distance Travelled =
speed x time
s = v x t
Acceleration =
change in velocity / time taken
(Final Velocity)² - (Initial Velocity)² =
2 x acceleration x distance
v² - u² = 2 x a x s
