Today we are going to finish the dynamics package that deals with basic F=ma questions and problems and we will start learning about... Crumple ZonesAn application of Newton's 2nd Law is something called Crumple Zones. We'll see how Newton's laws help explain these zones and just how useful they are.

Today is a work period. You will be completing the Newton's 2nd Law package fully and preparing for an upcoming quiz. We will investigate and learn about crumple zones tomorrow.
Net / Unbalanced ForceWhen using Newton's 2nd Law we must consider that it is the net / unbalanced force that causes an object to accelerate (speed up / slow down / change direction).
F = ma (Force = mass x acceleration) Newton's Second Law describes a universal relationship between the external, unbalanced force (F) acting on an object, the acceleration (a) of the object, and the mass (m) of the object. Newton's 2nd Law - LessonFrom the dynamics package you received in class; go through this guided lesson and then complete the two activities (solve simple questions with the equation and the 20 mark assignment). Learn MorePlease watch both of these videos to learn more about Newton's 2nd Law Today we are starting the Dynamics unit with an introduction to Newton's first of three very important laws. Today's law is the Law of Inertia (Newton's First Law).

Today we are writing a short quiz and then working on the review problems (handed out in class). Tomorrow we will start the dynamics unit and the test will be on Thursday.
