    ,      
  3. What is the equation for gravitational potential energy (GPE)
  4. What is the equation for kinetic energy?
  5. What is the equation for wave speed in terms of frequency(f) and wavelength (λ) ?
    v = f λ
  6. What is the equation for pressure due to a height of liquid or gas?
    • p = h ρ g
    • ρ = density of liquid (or gas)
  7. What is the equation for work done
    W = F d

    where d = distance moved in the direction of the force
  8. What is the equation for potential difference in terms of current(I), resistance(R)
    V = I R

    • V = potential difference
    • I = current
    • R = resistance
  9. What is the equation for resultant force in terms of acceleration(a)
    F = m a
  10. What is the equation for electrical energy used
    E = I t V

    • I = current
    • t = time
    • V = potential difference across component
  11. What is the equation for velocity
  12. What is the equation for the energy used to heat up an object
    E = m c Θ

    • m = mass of object
    • c = specific heat capacity of material
    • θ = temperature change
  13. What is the equation for acceleration


    • a = acceleration
    • v = final velocity
    • u = initial velocity
    • t = time taken
