Friction Lesson
0 Comments
Today we will do a short lesson discussing and learning about how the normal force is affected when in an elevator. We will consider conditions where the elevator is stationary, moving up (or down) at a constant speed, or accelerating up or down (while moving either up or down or from rest). The video below will also help with learning this important concept. What is the "Normal Force?"
The design and building phase of the egg drop challenge will be today.
Today is remembrance day - we are in an assembly during period 2. We went over a brief overview of the Egg Drop task prior to going to the assembly.
What is terminal velocity? What factors affect it?Websites and Terminal Velocity Calculators

Newton's 3rd Law: Action-Reaction Forces
Dynamics QuizWe are starting with 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.
Crumple Zones ActivityToday we are completing the Crumple Zones package (all questions as well as the Dynamics Practice Quiz from the package) and the two investigations: "Soft Landing" and "Hang Time" using the force plate and Logger Pro software.
We will be having a short dynamics quiz on Monday - related to the problems we have been doing and the practice quiz. 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.
