PHYSICS – Hey guys, here’s the lecture from Monday on vectors – graphical vector addition, resultants, and the like. Have you done anything like this before? We’ll spend tomorrow practicing adding vectors graphically. Great start today – and thanks for letting me play on the Smart board! Don’t forget your protractor and graph paper tomorrow!

Adding vectors graphically is tricky.

I have an awesome protractor that will make this pretty easy but im still wondering about a few things with these vectors.

Ms. Skinner,

Trig functions are a blessing.

.

So if you have two vectors plotted from the same point, could you find the hypotenuse from those two points or do you have to do head to tail?

So the whole mathematics method just involves using trig to find the ΔX and ΔY of anything not due N,E,S or W.

Ms. Skinner, I think I still need some help on adding those vectors.

Kamren – Did today help?

Do we have a topic for science in the news this week?

Jakin – Just physics.

Thanks for going over the component method again. It helped me to better understand how to use it.

the quiz is monday right

Yay! I understood the vector worksheet! I have a problem I plan on figuring out sometime this week, and if we have time, I think it’d be fun for the class to work it together for practice! I plan on figuring out which way from my house to church is faster by using vectors..my family has been arguing about it for years. Well, fear not Grices, because Physics Megan is here to save the day!

Megan – WhooHoo!! You do it – the Grice vector problem, I mean, and figure out how to work it into a presentation, and I’ll let it count in place of the Alternative Assessment that is due next Monday!
