Equations 1 weight = mass × gravitational field strength W = m g 2 work done = force × distance along the line of action of the force W = F s 3 force applied to a spring = spring constant × extension F = k e 4 distance travelled = speed × time s = v t 5 acceleration = change in velocity time taken a = ∆ v t 6 resultant force = mass × acceleration F = m a 7 HT momentum = mass × velocity p = m v 8 kinetic energy = 0.5 × mass × speed2 Ek = ½m v2 9 gravitational potential energy = mass × gravitational field strength g × height Ep = m g h 10 power = energy transferred time P = E t
11 power = work done time P = W t 12 efficiency = useful output energy transfer total input energy transfer 13 efficiency = useful power output total power input 14 wave speed = frequency × wavelength v = f λ 15 charge flow = current × time Q = I t 16 potential difference = current × resistance V = I R 17 power = potential difference × current P = V I 18 power = current 2 × resistance P = I 2 R 19 energy transferred = power × time E = P t 20 energy transferred = charge flow × potential difference E = Q V 21 density = mass volume ρ = m V
magnification = size of image / size of real object Rf = distance moved by substance / distance moved by solvent Photosynthesis: Carbon dioxide + water glucose + oxygen Respiration: Glucose + oxygen carbon dioxide + water Number of particles in moles = mass / formula mass Moles x Avogadros number = actual number of particles HT: Concentration = no. of particles in moles / volume of solution
