Very Short Question and Answers - Energy

The Sun is the biggest natural source of energy for us.

Solar energy, wind energy, and biomass are a few sources derived from the Sun.

In science, energy refers to the capability of an object to do work.

The wicket is thrown away due to the force exerted by the ball on impact.

Energy is measured in joules (J).

1 kilojoule is equal to 1000 joules.

James Prescott Joule was a British physicist known for his research in electricity and thermodynamics, and for formulating a law on the heating effect of electric current.

Mechanical energy consists of potential energy and kinetic energy.

Yes, energy can be transferred when one object exerts a force on another.

When an object loses energy, it does work on another object, transferring its energy either as motion or another form.

When a child winds a toy car, the mechanical energy stored in the spring transforms into kinetic energy when the car starts moving.

The shape of the balloon changes, and if pressure is excessive, it can explode.

Heat energy is the form of energy that is transferred between systems or objects with different temperatures.

Electric current possesses electrical energy.

Energy can be found in forms such as mechanical energy, heat energy, chemical energy, electrical energy, and light energy.

The object gains energy from the work done on it.

An object raised at a height has potential energy due to its position.

Kinetic energy is the energy an object possesses due to its motion.

Work is a transfer of energy; when work is done, energy is transferred from one object to another.

Yes, stationary objects can possess potential energy based on their position, but they may not have kinetic energy until they are in motion.
