Physics

Worksheet of all/most physics unit

Formulae

Energy = mass x SHC x temp change

K.E. = ½ mv2

P.E. = mgh

Work done (energy) = force x distance travelled

Force = mass x acceleration

Speed = distance / time

Acceleration = speed / time

Power = work done (energy) / time

I = Q/t

V=IR

P = IV

E = IVt

RT = R1 + R2 + R3 …

1/RT = 1/R1 + 1/R2 + 1/R3 …

Efficiency = useful energy/total energy x 100%

Moles = mass/molar mass

Moles = volume of gas (in dm3)/24

Moles = volume of solution (in cm3)/1000

Density = mass/volume

Hooke’s Law – force = constant x extension (F=kx)

V = f λ
