Nuclear Energy
Which point has the highest kinetic energy?
(Wait for Queen G)
Point Y
Which energy transformation produces electricity without causing pollution?
A) burning natural gas in a power plant to transform heat energy into electricity
B) spinning windmills to transform mechanical energy into electricity
C) each of the above options cause pollution
B
What is a disadvantage to non-renewable resources?
They cause pollution. They will run out.
What is the relationship between kinetic and potential energy?
As kinetic increases, potential decreases or vice versa.
When does a rubber band have the most elastic potential energy?
When it is fully stretched
What is one type of kinetic energy?

When a remote control car begins to move, what energy transformation is happening?
Chemical (potential) -> Kinetic Energy
How long are non-renewable resources expected to last?
50-100 more years
An acorn falls from a tree. How does it have both kinetic and potential energy?
THe acorn transfers potential energy to kinetic energy as it falls and picks up speed. It still has a position above the ground, so it has potential energy.
