Not sure if this is what Justin is saying but it is confusing when one equation has to be broken down into another equation in order to solve a problem.
Example from Thursdays homework:
P=W/t
P= (Fd)/t
P= (F)(V)
Obviously substitution isn't avoidable but when doing homework it would be nice to keep track of new equations in the notes... just saying. through post Mr. Wirth

I'm not sure I quite understand how to get to the certain equations you were using in class. I know we have the orignial equations but how do we know when to change them and which variables we need to find? It's hard to do the homework when don't have a clearer instruction.
Denise, Justin, Laura - You all make good points - Thank you. This is exactly the kind of conversation I am looking for!!
The object of problem #5 in Worksheet #2 was for you to work through each of the steps in the problem, leading you to the new equation of Power = Fv.
On Thursday, I purposely avoided pointing out the fact that the equation P=Fv was located in the reference tabled, so as not to spoil your hunt for it.
