Question

Classify the following example into kinetic energy and potential energy.
i]A compressed spring is released.
Ii]One marble strikes another in a game of marbles.
iii]The striker hits a coin on the carrom board.
iv]An arrow is released from a stretched bow.

Answer 1

1. potential
2. kinetic
3. kinetic
4. potential

Answer 2

The difference between kinetic and potential energy is the fact that kinetic energy is the energy of the moving object and potential energy is the one that creates the kinetic energy by transferring its energy onto another object.

Now for the classification, A compressed spring is released is the potential energy, one marble strikes another in a game of marbles and that is kinetic energy transferring from one of the object to another, the striker hits a coin on the carrom board and this is kinetic energy and finally an arrow is released from a stretched bow is the potential energy in the bow giving the arrow kinetic energy.
