Instructions: select all the correct answers. 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

2. A small rock sitting on the top of big rock.

3. a stretched rubber band.

Explanation:

The potential energy is defined as the energy by the virtue of the position of the object, its electric energy, stress which present in itself.

There are the two forms of potential energies which are more common:

Gravitational potential energy: It is a form of potential energy which depends on the mass of an object and the distance of that object from the center of the earth. In the given situation the rock which is sitting on the top of big rock posses gravitational potential energy.Elastic potential energy: It is the form of energy which is produced by the virtue of extending spring. This energy in this is the store energy of the extending or compressed spring. In the given situation a stretched rubber band is the example of elastic potential energy.

Therefore, in the given problem a stretched rubber band and  a small rock which is sitting on the top of big rock have stored energy.

Choice (3) would be one of the objects because when its stretching its waiting to release the energy. Then choice (1) would be the other object because when it rolls  the energy stored in the ball would be released when stopped. Therefore there storing the energy until released.  

Not what goes around on earth but the universe too.
