What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from mechanical energy to electrical energy.

Front

What energy transformation occurs when a hand generator is turned?

Back

Mechanical energy is transformed into electrical energy, which is then transformed into light energy.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for plants to convert carbon dioxide and water into glucose and oxygen, transforming light energy into chemical energy.

Front

What type of energy transformation occurs when a candle burns?

Back

Chemical energy stored in the wax is transformed into light energy and thermal energy.

Front

What energy transformations occur in a flashlight?

Back

Chemical energy from the batteries is transformed into electrical energy, which is then transformed into light energy.

Front

Define chemical energy.

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by the vibration of electrically charged particles.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object, which is the energy associated with its motion and position.

Front

Explain the process of photosynthesis in terms of energy transformation.

Back

Photosynthesis transforms light energy from the sun into chemical energy stored in glucose.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, which is the total kinetic energy of particles in an object.
