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 (of 4): Vocabulary and Formulas
Using a blank Cornell Notes page, take notes over the energy vocabulary and formulas below:
Using a blank Cornell Notes page, take notes over the energy vocabulary and formulas below:
* 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.
* Dissipated energy
Energy that is not transferred to make the object's velocity or height change. One example of dissipated energy is the energy that is 'wasted' to overcome friction. Dissipated energy is a form of kinetic energy.
* Mechanical energy
The total energy of an object (or system) is the sum of the potential and kinetic energies that it possesses.

* Mechanical energy
The total energy of an object (or system) is the sum of the potential and kinetic energies that it possesses.
* Law of Conservation of Energy
Energy cannot be created or destroyed; it simply changes form. The formula above for Total Mechanical Energy (TME) is based on the this law. When the total mechanical energy of a system is known, you can determine the way energy transfers within the system.

TASK TWO (of 4): Apply the Concepts
To observe these energy transformations, go to the Coaster Maker and build a Roller Coaster.

TASK THREE (of 4) : Show off your Coaster!
When you have build a successful roller coaster, take a screen shot of the design and post it on the padlet for your class:
