GCSE Physics mock EQUATIONS

all the equations we need to know for the physics mock 2026

distance, speed, time

distance travelled = average speed x time

speed = distance / time

acceleration, velocity, time

acceleration = change in velocity / time taken

a = (v - u) / t

force, mass, acceleration

force = mass x acceleration

F = ma

weight, mass, gravity

weight = mass x gravitational field strength

W = mg

momentum, mass, velocity

momentum = mass x velocity

p = mv

gravitational potential energy, mass, gravity, height

change in gravitational potential energy = mass x gravitational field strength x change in vertical height

ΔGPE = m x g x Δh

kinetic energy, mass, speed

kinetic energy = ½ x mass x speed²

KE = ½ x m x v²

efficiency

efficiency = useful energy transferred by the device / total energy supplied to the device

wave speed, frequency, wavelength

wave speed = frequency x wavelength

v = f x λ

wave speed, distance, time

wave speed = distance / time

v = x / t

work done, force, distance

work done = force x distance moved in direction of the force

E = F x d

power, work done, time

power = work done / time taken

P = E / t

moment, force, distance

moment of a force = force x distance normal to the direction of the force

energy, charge, potential difference

energy transferred = charge moved x potential difference

E = Q x V

charge, current, time

charge = current x time

Q = It

potential difference, current, resistance

potential difference = current x resistance

V = IR

power, energy, time

power = energy transferred / time taken

P = E/t
