Energy and Energy Resources

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, and chemical.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a pendulum at its highest point has maximum potential energy.

Front

What is renewable energy?

Back

Renewable energy comes from sources that can be replenished naturally, such as solar, wind, and hydropower.

Front

What is nonrenewable energy?

Back

Nonrenewable energy comes from sources that cannot be replenished in a short time, such as fossil fuels and nuclear energy.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What form of energy does the Sun produce?

Back

The Sun produces energy primarily through nuclear fusion, where hydrogen atoms combine to form helium, releasing energy.

Front

What is the difference between renewable and nonrenewable resources?

Back

Renewable resources can be replenished naturally, while nonrenewable resources are finite and will eventually run out.

Front

What is geothermal energy?

Back

Geothermal energy is heat energy generated and stored in the Earth, often used for heating and electricity generation.

Front

What is wind energy?

Back

Wind energy is the energy obtained from the wind, which can be converted into electricity using wind turbines.
