Types of Energy, Energy Transformations

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds between atoms in a molecule, which can be released during a chemical reaction.

Front

Define work in terms of energy transfer.

Back

Work is the transfer of energy by a force that moves an object over a distance.

Front

What type of energy is used by electrical devices?

Back

Electrical energy is the energy derived from electric potential or electric current.

Front

Where is maximum kinetic energy found on a roller coaster?

Back

Maximum kinetic energy is found at the bottom of a big hill on a roller coaster.

Front

What type of energy conversion occurs in a battery?

Back

A battery converts chemical energy into electrical energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

Explain 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 the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.

Front

Give an example of energy transformation in a light bulb.

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work.
