0
Three examples of chemical energy
food, fossil fuels, and batteries
Energy stored in chemical bond that hold together atoms and molecules
Chemical Energy
The total amount of kinetic and potential energy
Mechanical Energy
stored energy because of the way an object is stretched, bent, or compressed beyond its natural shape
Elastic Potential Energy
A pendulum has the most kinetic energy ___.
when it's at its midpoint.
What happens to molecules when you add or increase heat energy?
Energy due to an objects motion and position
Mechanical Energy
Energy in the form of moving waves of light
Gravitational Potential Energy depends on an item's
weight and height
Kinetic Energy depends on the objects ____ and ____

True or False
Sound energy can travel through space.
False
Energy resulting from the flow of electrons
Electrical Energy
Energy caused by an object's vibrations
Sound Energy

More massive and faster moving objects have _ kinetic energy.
more
Sound energy needs a _____ to travel through but light energy does not
medium
Energy produced from the splitting of an atoms nucleus
Nuclear Energy
Energy that flows from warm objects to cooler objects
Thermal (Heat) Energy
As a pendulum starts to move, what happens to its energy?
It moves from potential, to kinetic, back to potential.
Light energy can travel through _____ and/or_____.
a medium (matter) and/or empty space
