- 1Work out WeightW = Mass x gravitational field strength (g)
W = m x g - 2Work out the work donewd = force x distance (along a line of action of the force)
W = F x s - 3force applied to a springforce applied to a spring = spring constant x extension
F = k x e - 4moment of a forcemoment of a force = force x distance (normal to direction of force)
M = F x d - 5pressurepressure = force normal to a surface
__________________________
area of that surface
p = F / A - 6distance travelleddistance = speed x time
or speed = distance divided by time
s = v x t - 7accelerationacceleration = change in velocity
_____________________
Time taken - 8Resultant forceresultant force = mass x acceleration
F = m x a - 9momentummomentum = mass x velocity
p = m x v - 10kinetic energykinetic energy = 0.5 x mass x (speed)2
Ek = 0.5 x m x v squared - 11gravitational potential energyGrav potential energy = mass x grav field strength (g) x height
Ep = m x g x h - 12power 1power = energy transferred divided by time
p = W over t - 13power 2power = work done
___________
time - 14efficiencyefficiency = useful energy output transfer
_____________________________
total input energy transfer - 15efficiency 2efficiency = useful power output
____________________
total power input - 16wave speedwave speed (v) = frequency (f) x wavelength
- 17Charge Flowcharge flow = current x time
Q = I x t - 18Potential DifferencePotential Difference = current x resistance
V = I x R - 19Power 3power = potential difference x current
P = V x I - 20Power 4power = (current)2 x resistance
