W = m x g
Weight = mass x gravity
W = F x s
Work done = Force x distance travelled
F = k x e
Force applied to spring = spring constant x extension
M = F x d
Momentum = Force x distance
p = F / A
pressure = Force / Area of surface
s = v x t
distance travelled = speed x time
a = Δv / t
acceleration = change in velocity / time
F = m x a
Resultant force = mass x acceleration
p = m x v
momentum = mass x velocity
Ek = 1/2 x m x v2
kinetic energy = 0.5 x mass x velocity squared
Ep = m x g x h
Gravitational potential energy = mass x gravity x height
P = E / t
Power = Energy / time
P = W / t
Power = Work Done / time
Efficiency…
Efficiency = useful power output/total power output
v = f x λ
wave speed = frequency x wavelength
Q = I x t
Charge = current x time
V = I x R
Potential Difference = Current x Resistance
P = I x V
Power = current x potential difference
P = I x I x R
Power = current x current x resistance
E = P x t
Energy = power x time
E = Q x V
Energy = Charge x Potential Difference
P = m x v
density = mass x volume
