Motion+and+Energy

= Motion & Energy Flashcards = = = Absent? Lost or misplaced some of your flashcards? The entire list of flashcards for this unit is here.

= Newton's Laws of Motion = View Newton's Laws of Motion Interactive and work through all of the activities including Newton's biography, then take the quiz on Quia. The questions are the same as on the interactive, so pay attention!

= What Is Work? eClip = media type="custom" key="24365948"

View What Is Work. Afterwards, you need to answer the following questions on Quia. = =
 * What is the formula for work?
 * How is the amount of work needed affected by force and distance?

= Simple Machines = Go to Museum of Science and Industry: Simple Machines Game and play the game.

= Rube Goldberg Machines = Who is Rube Goldberg and what is a Rube Goldberg machine? Find out by going to the Rube Goldberg site.

Go to Goldberger to Go! and play the game.

= Extra Credit Project = Now it's your turn. Your task is to make a Rube Goldberg machine that **makes a simple task complicated** (much like the Rube Goldberg cartoons). It can be any task like turning on a light or putting food in your dog's bowl or watering a plant. You may work alone or with up to one other student. Your Rube Goldberg machine is to have at least 6 visible transfers of energy. Be sure to follow the guidelines given below. There is really no need to buy any special equipment, just use what you have at home like old toys, paper towel tubes, and duct tape. ** ( ** **Due: Friday, May 18th)**

Most importantly, get creative and have fun!
Special Rules:
 * No flammable or hazardous materials may be used.
 * No living plants or animals may be used.

Rubric:
 * Has a commentary that details each step that transfers energy.
 * Has at least 6 different steps. (I will not count steps that are repeated. In other words, all 6 steps can't be dominoes!)
 * Share a recording of your machine working by the due date.


 * Total points for the extra credit project = 30 points **

Watch the following video. He gives a lot of practical advice on the types of material to use and examples of how to use them. media type="youtube" key="_tranyqiryk" height="390" width="640"

Engineering students across the country participate in Rube Goldberg competitions designing machines that have the most complex designs to perform the simplest of tasks. The following is the 2011 entry by Purdue University's Theta Tau (a professional engineering fraternity) that shattered the world record for most steps (244 steps) completed by a Rube Goldberg machine. A "step" represents a transfer of energy. media type="youtube" key="xdPDn1KUz_A" height="345" width="560"

The following is a clip from Tom & Jerry. This is usually everyone's first time seeing a Rube Goldberg machine. Can you name some of the different simple machines that are shown in this cartoon? media type="custom" key="28604873"
