Physics Equations GCSE Year 10

(all equations for year 10 end of years)

Kinetic Energy =

0.5 x mass x (speed)²

Ek = ½ x m x v²

Elastic Potential Energy =

0.5 x spring constant x (extension)²

Ee = ½ x k x e²

Gravitational Potential Energy =

mass x gravitational field strength x height

Ep = m x g x h

Work Done =

force x distance

W = F x s

Power =

energy transferred / time

P = E / t

Power =

work done / time

P = W / t

Efficiency =

useful output energy transfer / total input energy transfer

Efficiency =

useful power output / total power input

Charge Flow =

current x time

Q = I x t

Potential Difference =

current x resistance

V = I x R

Power =

current² x resistance

P = I² x R

Energy Transferred =

power x time

E = P x t

Energy Transferred =

charge flow x potential difference

E = Q x V

Density =

mass / volume

p = m / V

Change in Thermal Energy =

mass x specific heat capacity x temperature change

Thermal Energy for a Change of State =

mass x specific latent heat

E = m x L

Weight =

mass x gravitational field strength

W = m x g

Distance Travelled =

speed x time

s = v x t

Acceleration =

change in velocity / time taken

(Final Velocity)² - (Initial Velocity)² =

2 x acceleration x distance

v² - u² = 2 x a x s
