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.
Unbalanced / Net ForceAs previously mentioned - it is the net/unbalanced force that cause objects to accelerate. So, to determine the acceleration of an object we must sum (add up) the forces acting on the object in a particular direction in order to determine the net force
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). My audio on my computer doesn't work with windows 10 so I had to just take a picture of the note...sorry. I made a video, but it had no sound. Learn more...Please 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).
Examples of Inertia...
The Amazing Egg Trick!...not really a trick...and maybe not totally amazing...but still cool.Today is the kinematics test. You have the full period to complete it. Good luck.
Today we are going to start the next unit: Dynamics - "the study of why things move." The title page and introductory powerpoint 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. Today we are going to do a mini-investigation where we will drop a stuffed toy animal from the Bearpit and calculate the height after measure the fall time. We will also discuss possible sources of error. I will post videos of this activity below...after we do the investigation.
Today we finished some example problems of simple projectile motion (objects falling or being thrown vertically). We also started the 15 question kinematics problems assignment. This comes in three parts. Part A are the basic types, Part B involve more thinking and Part C involve more complicated type problems. You are expected to solve all 15 in preparation for the upcoming evaluations. Today we are writing the 5 kinematics equations and solving some basic questions using these formulas. We are also going to have a short lesson on Gravity and the acceleration of gravity - using your investigations as a starting point.
