5 Explained the practical demonstration (i.e. why energy is converted from one form into
another).
6 Carried out a practical demonstration of an electric motor lifting a load on
7 Recorded measurements of the time taken to lift the load.
8 Explained the practical demonstration of electric motor (i.e. why energy is converted from
one form into another).
9 Carried out a practical demonstration the energy transformation of a solar cell on
10 Recorded voltage measurements for a range of angles between solar cell and lamp.
