Core Ideas:

  • For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first, but in the opposite direction (Newton’s third law).
  • The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion.
  • All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. In order to share information with other people, these choices must also be shared.

Learning Activities:

  1. Do Now– Get out your science notebook and add to the Table of Contents- “Driving Questions Summary Table- p.80” (Left Side) and “Driving Question Summary Table p.81” (Right Side). Open your science notebook to pages 80-81 and the “Motion, Forces, & Energy” textbook to page 36.
  2. Driving Question Board (DQB)– Retrieve post-it questions from your group’s poster, and write others if you have more. Put all your questions on DQB and organize the questions to come up with a driving question about motion and forces.
  3. Driving Question Summary Table– Set up Driving Question Summary Table on pages 80-81.
  4. Textbook Assignment– Read pages 36-39. Define key words on page 36. Answer all questions 1-2 on page 39.
