The gravitational forces between two masses are inversely proportional to
the square of the distance between the centers of the masses.
So if the distance between the <u>centers</u> of the asteroids is multiplied by 1/2,
then the gravitational forces between them are multiplied by ...
1 / (1/2)² = (2)² = 4 .
The new force is (100N) x (4) = <em>400N</em>.
Potential energy can be defined as the energy of something in relation to others, stresses within itself, or the electric charge.
Elastic potential energy the energy that is stored due to the deformation of an elastic object (i.e. a spring). This energy is equal to the energy needed to stretch the spring.
Chemical potential energy is energy stored in a substance's chemical bonds. This energy can be absorbed/released during either a chemical reaction or a phase transition.

Answer:
No.
Explanation:
We should not carry an umbrella during an thunderstorm. During thunderstorms, which are accompanied by lightning, electric discharge from the clouds can travle through the cloud metallic rod of the umbrella. This may give an electric shock to the person whos carrying it.

Answer:
Water in an artificial lake held behind a dam
Explanation:
Potential energy is energy that can be converted to kinetic energy, for example, an object at a certain height has potential energy because we can drop the object to have kinetic energy.
Therefore, the best example of potential energy is water in an artificial lake held behind a dam because without the dam, the water will start to move and it becomes the energy into kinetic energy.
