• gravity force

• kinetic energy

When a ball on a certain height is left to fall down,..........

• its kinetic energy changes into potential energy.

• its potential energy changes into kinetic energy.

• its potential energy remains as it is.

• its kinetic energy remains as it is.

A stopped object placed at 10 meters high from the Earth's surface has............... than the same object when it is placed at the ground.

• smaller potential energy

• smaller kinetic energy

• larger potential energy

• larger kinetic energy

We can see all the forms of energy

• True

• False

Energy can be stored in the form of potential energy

• True

• False

If an object has energy so it has ability to do work

• True

• False
