B. The Law of Conservation of Energy

What is the Law of

Energy can be ______________________ from one form into another or

Conservation of

Energy?

______________________ from one region to another, but the energy cannot be

__________________ or __________________

If energy is conserved,

Since there is always some _____________________ between surfaces that

how come when you

stop pedaling your

____________________ each other, _____________________ and

bicycle, you will

__________________________________ causes mechanical energy to change to

eventually come to a

stop?

___________________ (heat) with every movement.

Does the total amount

The _________________________________ (total energy) stays _________________.

of energy change?

Think about the energy transformation that occurs when you ride your bike…

1. You first need energy to get yourself to start riding a bike.

Where does this come from? _________________

•

What type of energy is this?__________________

2. Once you have ____________________ energy, this allows your leg and foot muscles to pump the pedals of

the bicycle.

What is this type of energy called? _________________

•

3. The pedals were first not moving, and therefore were storing _____________________ energy.

What does this type of energy transform into when you push down the pedal? _____________________

•

4. All of the parts of the bicycle are not moving thanks to ____________________ energy.

Since you are encountering friction during your bike ride, energy is being lost as _________________

•

What type of energy is this? __________________

•

Does the total amount of energy ever change? _____________

•

C. What are some forms of Energy Transformations?
