Phyiscs

With the new unit the simple multiplication is easy, but I am not certain when to use the cosine rule. Also, I am interested to see how effective this blog will be because I have never done something like this before.

I'm pretty sure I'm going to need more than two days of review for the midterm

weekend post (b/c we had to)

Just posting since we had to. Comments... this blog is an excellent idea for a higher level course to be quite honest. It has great potential but not so much with this course, there will be times where the blind will be leading the blind in these posts (no offense to anyone). Physics is also a very difficult course to just explain online. If someone doesn't understand something in class, it's most likely going to be harder to understand here. Simply calling a friend or asking others for help would be a much better alternative, so far it has been working for me.

I don't really understand what the dot product is. What does it solve for? What does "dot" mean? Also, all these vocab words and units are becoming hard to remember and not get mixed up.

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

The simple equations i have no problem understanding. It's just taking all of the equations that we learned and somehow every other equation goes into some other equations some how, and all of the variables just randomly come into equations they have no business being in.
