Two toy cars A and B of masses 500 g and 200 g respectively are moving with the same speed. Which of the two has greater kinetic energy?

A cyclist doubles his speed. How will his kinetic energy change: increases, decreases or remains the same?

Can a body possess energy even when it is not in motion? Explain your answer with an example.

Name the type of energy (kinetic or potential) possessed by the following:

(i) A moving cricket ball.

(ii) A stone at rest on the top of a building.

(iii) A compressed spring.

(iv) A moving bus.

(v) A bullet fired from a gun.

(vi) Water flowing in a river.
