Energy and Energy Transformations Review

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, chemical, and electrical.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's 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 is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, which determines its temperature.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or batteries.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is an example of energy transformation?

Back

An example of energy transformation is when a battery converts chemical energy into electrical energy to power a device.

Front

What happens to energy in a blow dryer?

Back

In a blow dryer, electrical energy is transformed into thermal energy to produce heat.

Front

At which point is kinetic energy highest in a pendulum swing?

Back

Kinetic energy is highest at the lowest point of the swing.
