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?Today we learned about the normal force and solved problems related to the normal force.
What is terminal velocity? What factors affect it?Newton's 3rd Law: ActionReaction ForcesLearn about Newton's 3rd Law: https://www.khanacademy.org/science/physics/forcesnewtonslaws/newtonslawsofmotion/v/newtonsthirdlawofmotion 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.
Dynamics QuizWe will start the class with a quiz about the basics of Newton's Second Law. Crumple Zone ActivitiesWe are going to see who can jump and land the "softest" on a force plate using the concept of crumple zones. Will also investigate hang times.
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.
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
