Law of Conservation of Energy

The Law of Conservation of Energy

Energy is not created nor destroyed

It is transferred/transformed from one type of energy to another.

Instructions

1. Get headphones

2. Go through the slides, watch the videos, and answer the questions.

3. When you get to the last 2 slides, get your workbook and add to your notebook according to the slides.

4. Answer the questions. You will be turning this in as part of your notebook portfolio.

Select answer

Dropdown

When the rock falls, what happens to its kinetic energy? ​

Select answer

Dropdown

When the rock falls, what happens to the sum (total) energy? ​

Select answer

Multiple Choice

The sum (total) of potential and kinetic energy in a closed system is called:

• Conservation of Energy

• Mechanical Energy

• Thermal Energy

• Potential Energy

• Kinetic Energy

Multiple Choice

True or false: The equation for mechanical energy only works if we don't count friction.

• True

• False

It's true. If we count friction then we get into more complex science which means we have to include thermal energy in the system. That means the equation is no longer valid as it's no longer a closed system.
