- 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.
- Do Now- Copy down today’s homework assignment in your planner. Open your science notebook to page 79. On the handout, write the vocabulary word “collision,” the meaning of the word as it is used in the text, and a sentence using the word. (Questions 1, 2, & 5)
- Reading Comprehension– “Crash Test” (Teacher Read-Aloud/Reciprocal Teaching in pairs)
- Unit Cover Page-On p.79 in your interactive science notebook, create a cover page for the unit on Motion and Forces
- Write the title very large so that it is easy to read.
- Draw a minimum of 3 pictures that represents the unit.
- Color the entire page, corner to corner, using colored pencil or crayons- no white paper showing
Motion and Forces Unit Cover page 79 due Friday, 5/12
