BTEC Applied Science Unit 1: Efficiency Worksheet Name____________ efficiency = ( 100 %) 1 What is the efficiency of a motor that turns 100 J of electrical energy into 70 J of useful kinetic energy? Give your answer as a decimal. 2 An electric winch is used to lift a load of mass 2 kg a height of 1.5 m. It uses 50 J of energy when it does this. i) Calculate the amount of potential energy gained by the load using the formula: Ep = mgh where Ep is the potential energy
