Question #4: How does energy flow in a system?

# data[].attributes.body
Energy can flow in a number of ways. For instance, mechanical energy from a bike can be turned into electrical energy to power a generator to power a burner that realeases thermal energy. Or take the sun, which releases light energy, which be turned into electrical energy by a solar panel, which can power a fan that releases mechanical energy.

Question #3: Can an object transfer more than one type of energy?

# data[].attributes.body
Yes, an object can tranfer more than than one type of energy. For instance, a campfire can transfer both thermal and light energy. Another example is a car’s motor because it is transferring sound and thermal energy.

Question #2: Can energy be created or destroyed?

# data[].attributes.body
No, energy can’t be crreated or destroyed. All energy starts out as one form or another. On the other hand, you can’t destroy energy because it just transforms into enother form of energy.

# data[].attributes.body
Yes, energy can change. For example, you can change light energy into electrical by using a solar panel. The electrical energy can then power a burner and turn into thermal energy.

# data[].attributes.body
Chemical energy is energy carried by the bonds in molecules.

# data[].attributes.body
Light, or radiant energy is energy carried by light. It is usually referred to as visible light. (ie, the sun)

# data[].attributes.body
Thermal energy is energy that is emited from heat. (ie, an active volcano or a stove thats on)

# data[].attributes.body
Sound energy is energy carried by sound waves. (ie, someone talking)

# data[].attributes.body
Electrical energy is energy carried by charged electric particle. It is also known as electricity. (ie, wall socket)

# data[].attributes.body
Mechanical energy is energy that an object has due to its motion or location (ie, a moving swing).

What is the Law of Conservation of Energy?

# data[].attributes.subject
What is the Law of Conservation of Energy?

# data[].attributes.body
The Law of Conservation of Energy states that energy cannot be created or destroyed, but that it can be changed.

# data[].attributes.body
Energy is defined as the ability to do work. Work is defined as applying force to move an object.
