(i) State what is meant by the term “potential energy” of a body.
(ii) A stone is raised to the top of a wall, while a spring is compressed by the same amount of work. Explain how the energy stored in the stone differs from the energy stored in the spring even though the numerical value of work done is equal in both cases.
(iii) A spring of natural length 20cm becomes 18cm long when a force of 10N is applied. Will the energy stored in the spring depend on the path taken while compressing it from 20cm to 18cm? Give a reason for your answer.
