edexcel GCSE Sciences: Physics Equations to Learn If you’re taking GCSE (9-1) Combined Science or GCSE (9-1) Physics, you need to know these equations: distance travelled = average speed x time change in velocity acceleration = Time taken force = mass x acceleration weight = mass x gravitational field strength (useful energy transferred by the device) efficiency = “—“ioial energy supplicd to the dovicey momentum = mass x velocity wave speed = frequency x wavelength wave speed = distance + time density = mass : volume work done = force x distance moved in direction of force E=Fxd change in gravitational potential nergy = mass x gravitational field strength x change in vertical height “CPE =m x g x Ah kinetic energy = % x mass x (speed)? KE=%xmxv? power = work done = time taken energy transferred = charge moved x potential difference charge = current x time potential difference = current x resistance power = energy transferred = time taken electrical power = current x potential difference electrical power = current squared x resistance force exerted on a spring = spring constant x extension If you’re taking GCSE (9-1) Physics, you also need to learn these extra equations: moment of a force = force x distance normal to the direction of the force pressure = force normal to surface + area of that surface P= zr
