Objective: To analyze the movement of a pendulum in order to describe the relationship between potential energy and kinetic energy in moving objects.CSI Note: What is Energy?Drill:
1. Get a ditto from the SET. 2. Read and highlight, “What is Energy”.
3. Think of questions you now have.
ENERGY: Kinetic vs. Potential
oneEEM-1A
WHAT IS ENERGY?Have you ever thought about.....why you are able to get out of bed in the morning
and come to school? Why the alarm clock sounds in the morning? How the toaster toasts bread? How your car runs? How
you run? Why your nose runs? How your computer runs? How everything runs?
NO, you say? WHY NOT?????? Do you not have enough energy? Funny, I said
energy, because that is the answer to all of the questions from above.
ENERGY: Kinetic vs. Potential
oneEEM-1A
Everything runs because of energy. In other words, energy is the stuff that makes stuff do stuff!!!!!! Or in proper scientific talk: the ability to do work or cause change. Work occurs when a force is acting over a distance. A force is any push or pull. In this investigation, you will examine and analyze objects at rest and in motion in order to describe the relationships that exist between the two types of stuff that make stuff do stuff (energy).

ENERGY: Kinetic vs. Potential
oneEEM-1A
There are two basic types of energy,
kinetic and potential.
ENERGY: Kinetic vs. Potential
oneEEM-1A
KINETICThe 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).

POTENTIALThe other basic type of energy is potential energy (P.E.). Potential energy is the opposite of kinetic energy. 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.
ENERGY: Kinetic vs. Potential

A specific type of potential energy that describes energy of position is known as gravitational potential energy (GPE). Potential energy can be stored in any object just because it occupies a higher position. The higher an object is the more GPE it 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. It has the greatest amount of gravitational potential energy when it is at its highest point. An object can have both kinetic energy and potential energy at the same time.
