Dragon Day #3: Energy Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or condition. For example, an apple hanging on a tree has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. For example, a moving car or a running person has kinetic energy.

Front

What type of energy do we receive from the Sun?

Back

We receive light or radiant energy and heat energy from the Sun.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object to another. For example, when you touch a hot stove, heat energy transfers from the stove to your hand.

Front

What does the law of conservation of energy state?

Back

The law of conservation of energy states that the total amount of energy in a closed system is always the same; energy cannot be created or destroyed.

Front

What is an example of potential energy?

Back

An example of potential energy is a stretched rubber band or a book on a shelf.

Front

What is an example of kinetic energy?

Back

An example of kinetic energy is a ball rolling down a hill.

Front

What is light energy?

Back

Light energy, also known as radiant energy, is the energy that travels in waves and can be seen by the human eye, such as sunlight.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy in food to kinetic energy when we move.

Front

What is mechanical energy?

Back

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