9. 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

10. 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

11. 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
