Which two objects have stored energy?
1_a ball rolling on the ground
2_a small rock sitting on top of a big rock
3_a stretched rubber band
4_a stone lying on the ground
Answers
2_a small rock sitting on top of a big rock ----> Gravititional potential energy
3_a stretched rubber band -----> elastic potential energy
A small rock sitting on top of a big rock = Gravitational potential energy
A stretched rubber = Elastic potential energy
Explanation:
In this case, we need to find the option that shows that objects have stored energy.
Option (1),
A ball rolling on the ground. The ball will have kinetic energy because it is in motion and moving objects posses kinetic energy only.
Option (2),
A small rock sitting on top of a big rock. It will have gravitational potential energy. It is a stored energy of the object.
Option (3),
A stretched rubber band. It will posses elastic potential energy. When the rubber band is stretched and then released, it will have elastic potential energy.
Option (4),
A stone lying on the ground. It will not possess any energy as it is stiff at the surface.
Hence, the correct statements are option (2) and (3).
