Class Set!!!!!!

There are two basic types of energy, kinetic and potential. The word
kinetic comes from the Greek word kinetos which means "moving.”
Therefore, kinetic energy (K.E.) is simply described as energy of motion. If
an object is moving, it has kinetic energy. Two factors that affect the
amount of kinetic energy an object has are mass and velocity (speed). The
other basic type of energy is potential energy (P.E.). Potential energy is the
opposite of kinetic energy. If kinetic energy is energy of motion, potential
energy is energy that exists even when an object is at rest. It can be simply
described as stored energy or energy that has the potential to do work.
Potential energy can be the result of an object's position, shape, or chemical
make-up. Kinetic energy is the result of potential energy being converted to
action. A specific type of potential energy that describes energy of position
is known as gravitational potential energy (G.P.E.). Potential energy can be
stored in any object just because it occupies a higher position. The higher
7. object is the more G.P.E selection to evaluate y
an Use the information in the readingit has. The kinetic energy resulting from the
conversion of gravitational potential energy to an object's movement is
readily visible. Furthermore, a simple relationship exists. A falling object
has its greatest amount of kinetic energy when it is traveling its fastest.
Did you label your pendulum correctly with kinetic and potential
energy?

1. Observe the diagram and read caption.

Stanley Stick wants to drop his ball
off of a cliff to show that the ball
has more energy just before it hits
the ground. He said, "The ball has
Exit # 1                                   more energy just before it hits the
ground because it is going fastest
there! It has no energy at the top,
because it is not moving!!!"

2. Label the diagram with the points of maximum and minimum potential energy and kinetic energy.
Explain the error(s) in Stanley's thinking using information from today's investigation. You may
use the diagram to help support your explanation.

3. Not all of the potential energy that exists at the top is directly converted to the downward
movement and speed that the ball rolls. Determine what happens to this "lost" energy, can energy
be lost? (HINT: Think about friction and the law of conservation of energy).
