Physics 10-24-22 Did the Hammock Crash? and A Street Sign Askew

Posted on by

PHYSICS: Great work today thinking through these problems! How you look at problems from the beginning can make a huge difference – huh?

A couple of things that work for me when doing equilibrium, etc., problems – first, draw them. Then go back through and separate resultants into components. If an object is in equilibrium, then there are no net forces – all the forces in the x direction balance – everything left equals everything right, and all the forces up equal all the forces down.

You’ve got all the ammo you need, now go forth and conquer pumpkins! And Zorba!!

Answers for the Equilibrants II worksheet are below:

  1. Fn = 3430 N upward against feet
  2. Fn1 = Fn2 = 1890 N upward on each foot
  3. F forward = 4.59 N
  4. T1 = T2 = 1760 N
  5. T1 = 1360 N and T2 = 680. N

Chemistry 10-24-22 Chapter 1 Test Overview

Posted on by

CHEMISTRY – Are you ready? God bless you as you study! Here’s our overview of chapter 1 and the test – good stuff!!

Make sure you aren’t just reading your book and notes. First, memorize the facts, then go back and make sure you can apply the concepts. Study examples, make your own examples, practice making questions. And don’t forget, if you are getting lost with everything you need to know, or if you’re not sure how to study, Chapter 1 Stuff to Know Sheet under the Test Info tab.

If you want some interactive practice for the test (GREAT IDEA!!) here are a couple of great reviews from The Physics classroom. These are optional, so sign on as “Guest” if you want to do them:
Chemical vs. Physical Properties
Metals, Nonmetals & Metalloids
States of Matter
Energy & Chemical Changes
Classification of Matter

 

Also remember there are great review games that are in the Student Premium section of the online textbook. You can do this – I believe in you! I’m praying for you!!
