A Teacher parks his car at the top of a tall hill. He forgets to put the hand brake on and it begins to roll down the hill. Complete the energy transfer for this.
(hint two stages)
A student slaps his hand on to the table. Which energy transfer will occur?
A lump of coal has 200J of chemical energy inside it.
150J is released as thermal energy when it burns.
How much energy is released as light energy?
What is the equation used to calculate efficiency?
A car burns 2000J of petrol. The car produces 1000J of kinetic energy. What is the cars efficiency?
An ipod uses 1000J of energy. 800J goes into making light and sound. The rest of the energy is wasted. How much energy is wasted?
