(a) (i) State the principle of conservation of energy. [1 mk] (ii) Identify the main energy conversion process that takes place in: (1) a burning candle [1 mk] (2) a lit light bulb [1 mk] Define the term "potential energy" [1 mk] (iv) Give ONE example of a body possessing potential energy. [1 mk] Define the term 'kinetic energy' [1 mk] (b) At a football match between two college teams, the referee ordered a free kick. The ball of mass 1.5 kg was placed at rest. The kick was about to be taken by an eager footballer. What was the potential energy of the ball just before the kick was taken? [1 mk] (c) The footballer kicked the ball and it was caught by the opposing goalkeeper, 4 meters above the ground. The ball was travelling at 10 ms (i) Calculate the potential energy of the ball just before it was caught. [2 mks] (ii) Calculate the kinetic energy of the ball just before it was caught. [1 mk]
