Chapter 3: Work

Chapter 3 builds on what students learned in Chapter 2. Now instead of E1 = E2; the equation becomes E1 + Work = E2.

Students will learn how to ...

  • determine the work done by a force;
  • factor in work done by different forces;
  • measure the force of friction;
  • use a slingshot to launch a box across the ground so it stops at a certain spot.
