Energy Transformations Review

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy into thermal energy.

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

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 a substance.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the top of a hill has gravitational potential energy.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What happens during photosynthesis?

Back

During photosynthesis, plants convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.

Front

What is an example of mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object. An example is a moving car.

What is the role of a thermometer?

Back

A thermometer is a tool used to measure the average kinetic energy of particles in a substance, which is perceived as temperature.

Front

What is light energy?

Back

Light energy is a form of electromagnetic radiation that is visible to the human eye and is produced by sources like the sun and light bulbs.
