Forms of Energy

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye. It is produced by the movement of photons and is used in processes like photosynthesis and solar panels.

What is mechanical energy?

Back

Mechanical energy is the energy associated with the motion and position of an object. It can be kinetic (energy of motion) or potential (stored energy due to position).

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object and is often felt as heat.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices and appliances in our homes.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It travels through air, water, and solids.

Front

How do solar panels work?

Back

Solar panels convert light energy from the sun into electrical energy using photovoltaic cells.

Front

What is an example of an activity that uses mechanical energy?

Back

Riding a bicycle is an example of an activity that uses mechanical energy, as it involves the movement of the bike and the rider.

Front

What is the role of turbines in dams?

Back

Turbines in dams convert the mechanical energy of flowing water into electrical energy.

Front

What is photosynthesis?

Back

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

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.
