Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting potential energy to kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as gravitational potential energy.

What happens to kinetic and potential energy in a pendulum?

Back

As a pendulum swings, kinetic energy is highest at the lowest point, while potential energy is highest at the highest points.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its height above the ground, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

What is an example of energy transformation in a microwave oven?

Back

In a microwave oven, electrical energy is transformed into thermal energy (heat) and light energy.

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 chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules, which can be released during a chemical reaction.

Front

How does a plant convert light energy?

Back

A plant converts light energy into chemical energy through the process of photosynthesis, creating glucose from carbon dioxide and water.

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.
