Lesson 15 notes – Newton 1 and 3 - science
... Without looking at your notes, define (a) Newton’s First Law, (b) Newton’s Second Law and (c) Newton’s Third Law. (a) Newton’s first law states that an object will remain stationary or continue at a constant velocity unless acted on by a resultant force. (1) If it is acted on by a resultant force it ...

... The fact that a wall or other passive object can exert a force is a new and important concept for students. In addition to the demonstrations with dynamics carts shown in Figure 2.33, you might look at the many action-reaction and thrust demonstrations in DHP, pages M-17 to M-25. Discuss challenge 4 ...

... **108 As part a of the drawing shows, two blocks are connected by a rope that passes over a set of pulleys. One block has a weight of 412 N, and the other has a weight of 908 N. The rope and the pulleys are massless and there is no friction. (a) What is the acceleration of the lighter block? (b) Sup ...
