Energy Transformation

Front

What does the Theory of the Conservation of Energy state?

Back

Energy can never be created nor destroyed. It can only change its form from one type to another.

Front

What type of energy transfer occurs when food is digested?

Back

Chemical to mechanical.

Front

What is the correct order of energy transformations when green plants produce food from the Sun’s energy?

Back

Light → chemical.

Front

What type of energy do we receive from the Sun?

Back

Light and heat energy.

Front

What energy transformation occurs when a flashlight shines?

Back

Chemical → electrical → light.

Front

Define energy transformation.

Back

The process of changing energy from one form to another.

Front

What is kinetic energy?

Back

The energy of an object due to its motion.

Front

What is potential energy?

Back

The stored energy of an object due to its position or state.

Front

Give an example of energy transformation in a hydroelectric power plant.

Back

Potential energy of water is transformed into kinetic energy as it flows, which is then converted into electrical energy.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy from the Sun, which is then transformed into chemical energy.
