5/1/17

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.
