Dynamics QuizToday we are having a short dynamics quiz. Weight and Mass are NOT the same thing!!Today we are learning the difference between mass and weight...we are also reviewing density and volume from grade 9.
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.
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).
Simple Online CalculatorThe calculator below can be used to solve simple F=ma questions. It will calculate the net force, mas or acceleration depending on which variable you are required to solve for.
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 -Lesson

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).
Examples of Inertia
The Amazing Inertia Egg Trick!Introduction to DynamicsToday we are going to start the next unit: Dynamics - "the study of why things move." The title page and introductory Power-Point are included below. Watch the documentary on Newton as well. We are also continuing with the work and review for the kinematics test tomorrow. Be sure to complete the yellow sheet of questions and the package with 4 additional problems. Newton's Dark Secret
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.
There is a trip out today so we are going to have a work period (completing the yellow kinematics problems sheet). I will also hand out the review package for the final evaluation that we will work on tomorrow along with the short quiz.
