Frictional Forces

ms. K gave us this sheet, titled Frictional Forces, we did answer the questions on it and the third and fourth images are the answer key...

Inclined Plane

Today, four groups answered the questions on page 196, 1 number per group. But only number 3 was solved on the white board. (Second image)
Ms. K also gave an example of a diagram about Forces acting on an inclined plane. (Third image)
We also answered the questions on page 18 of the booklet for Dynamics Unit. The answers are on the back of the booklet.








**We will do Lab experiment about inclined plane tomorrow

(continuation) static equilibrium problems

Today, we read lessons regarding frictional force, normal force and inclined planes from the textbook. There's an assignment on p. 196 numbers 1-4. Ms. K said that the we will a do lab on Tuesday about inclined planes.

We also answered the static equilibrium problems # 3-5.

**If you're given the mass of the object, solve first for the weight.

**Draw your triangle with its corresponding angles, then solve for the unknown side which is Ft(tensional force) in this case. Solve it by using trigonometric identies.

THURSDAY & FRIDAY

On Thursday we went over the Acceleration I & II worksheets, we were individually assigned a question from each to illustrate our answers on the board.

Well I'm not going to write down the answers because it will waste too much of my time; if you weren't there or chose to be negligent to not copy down the answers, then please get them from a classmate or try them on your own. They are not difficult. :P

On Friday, were assigned pages 95-103 to read on RELATIVE MOTION in the IRWIN PHYSICS TEXTBOOK. On page 103, concept questions were assigned 1-2.c. beneath the figure 3.38.

Of course many students signed out textbooks for the weekend. Did you borrow one? Please try return it before the test tomorrow! Oh, and good luck! Refer to Chemutai's post to assist you in deriving formula's from different types of Displacement-Time graphs!
