FHSST is a project that aims to provide free science and mathematics textbooks for Grades 10 to 12 science learners. The project was initiated by young South African scientists, and now brings together scientists from around the world who are willing to contribute to the writing of the books.<p/> Below is a complete Table of Contents for this chapter.<p/> <b><p>This resource is part of the <a href=\"http://www.curriki.org/oer/Physics-42760\">FHSST Physics</a> collection.</p></b><p/> <p><b>CONTENTS</b></p> <p><b>III GRADE 11 – PHYSICS</b></p> <p><b>Chapter 12: Force, Momentum and Impulse - Grade 11</b></p> <p>12.1 Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 239</p> <p>12.2 Force . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 239</p> <p>12.2.1 What is a force? . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 239</p> <p>12.2.2 Examples of Forces in Physics . . . . . . . . . . . . . . . . . . . . . . . 240</p> <p>12.2.3 Systems and External Forces . . . . . . . . . . . . . . . . . . . . . . . . 241</p> <p>12.2.4 Force Diagrams . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 242</p> <p>12.2.5 Free Body Diagrams . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 243</p> <p>12.2.6 Finding the Resultant Force . . . . . . . . . . . . . . . . . . . . . . . . . 244</p> <p>12.2.7 Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 246</p> <p>12.3 Newton’s Laws . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 246</p> <p>12.3.1 Newton’s First Law . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 247</p> <p>12.3.2 Newton’s Second Law of Motion . . . . . . . . . . . . . . . . . . . . . . 249</p> <p>12.3.3 Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 261</p> <p>12.3.4 Newton’s Third Law of Motion . . . . . . . . . . . . . . . . . . . . . . . 263</p> <p>12.3.5 Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 267</p> <p>12.3.6 Different types of forces . . . . . . . . . . . . . . . . . . . . . . . . . . . 268</p> <p>12.3.7 Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 275</p> <p>12.3.8 Forces in equilibrium . . . . . . . . . . . . . . . . . . . . . . . . . . . . 276</p> <p>12.3.9 Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 279</p> <p>12.4 Forces between Masses . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 282</p> <p>12.4.1 Newton’s Law of Universal Gravitation . . . . . . . . . . . . . . . . . . . 282</p> <p>12.4.2 Comparative Problems . . . . . . . . . . . . . . . . . . . . . . . . . . . 284</p> <p>12.4.3 Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 286</p> <p>12.5 Momentum and Impulse . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 287</p> <p>12.5.1 Vector Nature of Momentum . . . . . . . . . . . . . . . . . . . . . . . . 290</p> <p>12.5.2 Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 291</p> <p>12.5.3 Change in Momentum . . . . . . . . . . . . . . . . . . . . . . . . . . . . 291</p> <p>12.5.4 Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 293</p> <p>12.5.5 Newton’s Second Law revisited . . . . . . . . . . . . . . . . . . . . . . . 293</p> <p>12.5.6 Impulse . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 294</p> <p>12.5.7 Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 296</p> <p>12.5.8 Conservation of Momentum . . . . . . . . . . . . . . . . . . . . . . . . . 297</p> <p>12.5.9 Physics in Action: Impulse . . . . . . . . . . . . . . . . . . . . . . . . . 300</p> <p>12.5.10Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 301</p> <p>12.6 Torque and Levers . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 302</p> <p>12.6.1 Torque . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 302</p> <p>12.6.2 Mechanical Advantage and Levers . . . . . . . . . . . . . . . . . . . . . 305</p> <p>12.6.3 Classes of levers . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 307</p> <p>12.6.4 Exercise . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 308</p> <p>12.7 Summary . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 309</p> <p>12.8 End of Chapter exercises . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 310</p> </p>
