Physics 11-Position-time graphs

The link above (click the title of this post) will take you to one of my favorite sites for physics. It will explain the topic and give you some questions to try with a link to check your answers. At the bottom of each lesson there will be a link to advance to the next section. If you can, work your way through to the end of Lesson 4.

Bad Roads and Pre-Calc

So, on day two of bad roads I thought I'd make a quick post just in case you had your work at home with you. The truth of the situation is that if we don't cover this lesson now, we'll have to double up somewhere down the road.

The link above (click on the title of this post) will take you to a lesson on Trig equations-it solves equations in the general case. That is what the "n" is about-if you like you can ignore the "n" for now and we'll cover it tomorrow.

Enjoy the day!

Exercise #7: Slope

If you happen to have your work with you, here's a straight forward lesson to get out of the way.

PC 12-Exercise 4

The link above will take you to today's notes. I'm going to place a link to my first class page and try to post class notes regularly so that if you miss a class you can still check the blog.

Distance Between Points

Hi there dedicated math student...

Watch the video below and give exercise #4 a try. If there are questions you have that I don't get to in class today, you can leave a comment below and I can answer them here.

Let me know what you think by leaving a comment.

Physics 12 Exam tomorrow

Apparently the weather is supposed to warm up and I'm guessing that it'll be business as usual tomorrow. This means for you that you will have your exam tomorrow as planned. I've seen many of you already, but for those I haven't the link above will take you to the key for another practice exam.

Good luck. See you tomorrow.

Orbits

Today we discussed two types of orbit. Circular orbits (involving satellites around a planet), and elliptical orbits (planets around the sun).

For circular orbits we can equate centripetal force with the force due to gravity to arrive at a formula for orbital velocity:


While for planetary orbits we looked at Kepler's Laws.

I also gave you an old exam to study from so please use your time well this week since our exam is only a week this Friday away.
