Chapter 2 Review

Forces Study Guide

The “big idea” for our forces unit is: Forces influence the motion of an object. Below is a list of all the problem sets and other work from the unit. Any of the questions from the unit would be fair game for the test, but if you’re just looking for a select few to highlight some key concepts, I’d recommend doing the following…

Problem Set 2.1

• Do one of these questions.

Problem Set 2.2

• Do two of the diagrams from question 2.

Problem Set 2.3

• Do two of the FBDs and two of the numbered questions.

Problem Set 2.4

• Do #4 and #5.

Problem Set 2.5

• Do #8, #9, #10.

Problem Set 2.6

• Do #1, #5, and one question from the back side.

Finding Friction Activity

• Look at page 3. For cases 2, 3, and 4, be able to say whether we would expect friction to be higher, lower, or the same compared to case 1. Which cases would you expect to have the same coefficient of friction, and which case(s) would you expect to have a different one?

Problem Set 2.7 (Part 1)

• Do one question.

Problem Set 2.7 (Part 2)

• Do one question.

Problem Set 2.8

• Do one question.
