Q & A

What is energy?

Energy is the ability to do work.

In what forms can energy be found?

Energy can be found in various forms, including kinetic energy, potential energy, chemical energy, electrical energy, and gravitational energy.

How does the body obtain energy from food?

When you eat, your body breaks down the food, releasing energy that allows you to work and play.

What is kinetic energy?

Kinetic energy is the energy of an object in motion.

What is potential energy?

Potential energy is the energy stored in an object when it is not moving, which can do work when released.

Can you give an example of potential and kinetic energy using a ball?

When a ball is at rest, it has potential energy. Once it is pushed and starts rolling, it possesses kinetic energy.

What is the principle of conservation of energy?

Energy cannot be created or destroyed; it only transforms from one form to another.

What is mechanical energy?

Mechanical energy is the sum of potential and kinetic energy in an object at the same time.

What role does chemical energy play in digestion?

Chemical energy is released during digestion when food is broken down.

How is energy used in a light bulb?

Only 10 percent of the energy in a light bulb is used to create light; the remaining 90 percent generates heat.
