The objective of this lesson is to provide you with an introduction to
transferring energy
when the position of an object (height) changes
to cause a subsequent change
in the speed of the object (velocity).
TASK ONE: Vocabulary and Formulas
Summarize the information below using Cornell Notes.
* Law of Conservation of Energy
Energy cannot be created or destroyed; it simply changes form.
The formula for Total Mechanical Energy (ME) is based on the this law. When the total mechanical energy of a system is known, energy transfers within the system can be evaluated.

* Mechanical energy
The total energy of an object (or system) is the sum of the potential and kinetic energies that it possesses.
The total Mechanical Energy of a closed system remains constant.
The total energy of an object (or system) is the sum of the potential and kinetic energies that it possesses.
The total Mechanical Energy of a closed system remains constant.
* Closed System
No energy flows into or out of a closed system. Systems are defined by the observer.

POTENTIAL ENERGY: There are several types of potential energies including Elastic Potential Energy, Chemical Potential Energy and Gravitational Potential Energy. Potential energy is based on position. We will begin our study of potential energy with Gravitational Potential Energy.
* Gravitational Potential Energy
Energy of an object due to its position in a gravitational field. Objects gain
Gravitational Potential Energy by moving higher in a gravitational field.
Energy of an object due to its position in a gravitational field. Objects gain
Gravitational Potential Energy by moving higher in a gravitational field.
* Kinetic energy
Energy of an object due to its motion. Objects gain Kinetic Energy by moving faster.
Energy of an object due to its motion. Objects gain Kinetic Energy by moving faster.
TASK TWO: Falling Ball Energy Analysis
Use LoggerPro Graphs to analyze the energy transformations. You will be provided with copies of these in class. You can print another copy if you need it.
