All LE and UF equations

speed

speed = distance/time

acceleration

acceleration = change in velocity/time

(final speed)2

(final speed)2 = (initial speed)2 + 2 x acceleration x distance moved

force

force = mass x acceleration

weight

weight = mass x gravitational field strength

momentum

momentum = mass x velocity

force

force = change in momentum/time taken

moment

moment =

force x perpendicular distance from pivot

orbital speed

orbital speed =

(2 x pie x orbital radius)/time period

voltage

voltage = current x resistance

charge

charge = current x time

energy transferred

energy transferred = charge x voltage

power

power = current x voltage

energy transferred

energy transferred =

current x voltage x time

wave speed

wave speed = frequency x wavelength

frequency

frequency = 1/time

refractive index

n = sin(i)/sin(r)

critical angle

1/refractive index

1/n

density

density = mass/volume

pressure

pressure = force/area

pressure difference

pressure difference = height x density x gravitational field strength

energy transferred/ change in thermal energy

change in thermal energy =

mass x specific heat capacity x change in temp.

work done

work done = force x distance moved

gravitational potential energy

GPE = mass x gravity x height

kinetic energy

kinetic energy = ½ x mass x speed2

power

power = work done/time taken
