Energy unit

Here are the objectives for the energy unit.

  • Calculate the effective force in a given situation (the component of the applied force parallel to the direction of motion)
  • Applies the relationship between work, effective force and distance travelled (W = FΔd)
  • Applies the relationship between work and energy (W = ΔE) – not covered on the test
  • Applies the relationship between potential energy, mass, gravitational acceleration and the distance travelled (Ep = mgh)
  • Applies the relationship between kinetic energy, mass and speed (Ek= ½mv²)
  • Applies the relationship between thermal energy, mass, specific heat capacity and temperature variation (Q = mcΔT)
