Do Simple Machines Homework 1 & Simple Machines Homework 2 in class. Hand them in when you are done.


Read over the Simple Machines Notes.

Work on Simple Machines Classwork 99 in small groups. Then check with other small groups to see if you are getting the same answers. When done, if there are questions that you have, e-mail me so I can try and clear them up. Simple Machines is mathy and some people need a little extra explanation. rkrall@sayresd.org


Use answer keys to check your work on Simple Machines Classwork 2, Simple Machines Classwork 3, and Simple Machines Basics Practice.

Correct any mistakes you may have.

Homework - Work & Machines Homework 1

Classwork - Work & Machines Classwork 1 - Check your answers here.

Notes - Work & Machines Notes - Read these over. The big idea is that the total work you put in a machine is the same amount that comes out of the machine. Since Work = Force * Distance, the machine can still do the same work as you, but with different F*D numbers.

Ex. You put in 5 force and 10 distance for 50 Joules of work, and the machine gives out 50 Joules of work, but in the form of 25 force and only 2 distance. 5*10 is the same total as 25*2.
