GCSE Physics equations to learn

Question	Answer
Distance travelled	Distance travelled = speed x time
Acceleration	Acceleration = change in velocity / time taken
Force	Force = mass x acceleration
Weight	Weight = mass x gravitational field strength (N)
Efficiency	Efficiency = useful energy transferred by the device/total energy supplied to the device
Momentum	Momentum= mass x velocity
Wave speed	Wave speed = wavelength(λ) x frequency
Wave speed	wave speed = Distance(x)/time
Density	Density = mass/volume
Work done	Work done = Force x distance moved in the direction of the force
Change in gravitational potential energy	ΔGPE = mass x gravitational field strength x Δheight
Kinetic energy	KE= 1/2 x mass x (speed)²
Power	Power = work done / time taken
Energy transferred	Energy transferred = charge moved x potential difference
Charge	Charge = current x time
Potential difference	Potential difference = current x resistance
Power	Power = energy transferred / time taken
Electrical power	Electrical power = current x potential difference
Electrical power	Electrical power = current² x resistance
Force exerted on a spring	Force exerted on a spring = spring constant x extension
Momentum of a force	Momentum of a force = force x distance normal to the direction of the force
Pressure	Pressure = force normal to surface / area of the surface
