Test Friday

Okay people Simple Machines is coming to a close. Our test is soon and the following topics will be covered: 

• All 6 Types of simple machines
• Lever, Pulley, Wedge, Inclined Plane, Wheel & Axle, Screw
• The input force and output force of all the simple machines
• What Work means. The force on the object and the motion MUST be in the same direction!
• Work = Force x Distance (we measure work in Joules)
• Mechanical Advantage = Output Force / Input Force
• Mech. Advantage means how many times the force is multiplied by the machine
• Efficiency = (Output Work / Input Work) x 100
• Efficiency is how well the machine is working. It is ALWAYS less than 100% because we always 'lost' some force to friction

CP: You're taking the test on Friday so tomorrow is your last day in class to finish the review and ask me any questions. I will be available at lunch and after school. These links are answer keys to materials we have had in class: 

Input and Output Forces

Efficiency Notes

Mechanical Advantage Notes

How to make a flipchart to study (These were done in class today!)

CP Test Review Homework


Work, Mechanical Advantage, and Efficiency Practice


Honors: 001 You'll be taking the test tomorrow. 002 you'll be taking Friday. I'm sure you're all ready for it. Either way, I've attached your materials as well: 

Input and Output Forces

Efficiency Notes


Mechanical Advantage Notes

Honors Test Review Homework


Work, Mechanical Advantage, and Efficiency Practice


Good luck studying and e-mail with any questions!
