Physics
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.
(vii) A stretched rubber band.
Answer
(i) A moving cricket ball has kinetic energy due to its state of motion.
(ii) A stone at rest on the top of a building has potential energy due to its raised position.
(iii) A compressed spring has potential energy due to its compressed state.
(iv) A moving bus has kinetic energy due to its state of motion.
(v) A bullet fired from a gun has kinetic energy due to its state of motion.
(vi) Water flowing in a river has kinetic energy due to its state of motion.
(vii) A stretched rubber band has potential energy because of its stretched position.
