λ = v/f
Wavelength = wave speed / frequency
d = s x t
Distance travelled = speed x time
A =(v - u) / t
Acceleration = change in velocity/time
F = m x a
Force = mass x acceleration
W = m x g
Weight = mass x gravitational field strength
P = m x v
Momentum = mass x velocity
∆GPE = m×g×∆h
Change in gravitational field potential
KE = 0.5 x m x v2
Kinetic energy = 0.5 x mass x velocity2
v = d/t
Wave speed = distance/time
E = f x d
Work done = force x distance
P = E/t
Power = work done / time
E = Q x V
Energy transferred = charge moved x potential difference
Q = I x t
Charge = current x time
V = I x R
Potential difference = current x resistance
P = E / t
Power = energy transferred / time
P = I x V
Electrical power = current x potential difference
P = f2 x r
Electrical power = current2 x resistance
D = m/v
Density = mass/ volume
F = k x X
Force = spring constant x extension
P = f/a
Pressure = force normal to surface / area of surface
v2 −u2 =2×a×x
(final velocity)2 – (initial velocity)2 = 2 × acceleration × distance
