Warm Up:

CLICK HERE to be taken to quiz on Newton’s Laws of Motion.

Room Number is “A89559b4”

Agenda:

The first thing we are going to do today is complete a Webquest to reinforce our understanding of Newton’s First and Second Laws as well as Free-body diagrams. While completing the Webquest, you will answer questions on the student handouts found below and take written notes.

It is recommended that you use headphones during Part I of the Webquest, as there is a short video for you to watch. However, if headphones are unavailable, you can watch the video at a low volume.

Handout:

Demonstrations of Newton’s Third Law:

For this demonstration,we will need two rolling chairs and the whiteboard.

First demonstration:

1. We are going to begin by having two students sit in rolling chairs facing each other. Students will gently push off of each other’s hands (so that they move away from each other).
2. After this I will then draw the two students on the board and label all forces (normal force, gravity, friction, push by the student, push from other student) on each student. Students, I want you to follow along with me.
3. After the initial drawing,  students are going to draw a free body diagram to go with their drawings. A free body diagram is one that shows the forces acting upon an object. Example: Reminder:

On your drawings, the direction of the student’s acceleration should be indicated. The direction of acceleration is the same direction as the push by the other student, not the push given by the accelerating student.

Question:

Why did the rolling students eventually slow down and stop? (Hint: Newton’s First Law.)

Second Demonstration:

1. I now need a student to sit on a rolling chair facing a wall. The student will push off the wall and roll away.
2. Again, draw the student and all forces. Don’t forget to include the push from wall!
3. At this point, lets review Newton’s Second Law.  What is providing the force of the acceleration? Hint: The harder the student pushes, the harder what pushes back and thus the faster the student accelerates?
4. Further demonstration of Newton’s Third Law. Check out this tutorial for how to step off a boat: Man Steps Off of Boat

Final Demonstration:

• How are you able to move forward while walking? Which way do you push with your foot while walking?
• Draw a diagram of a foot pushing off to walk. Which forces are acting on the foot? (Hints: Normal Force, Gravity, and Push by Foot
• Now apply Newton’s Second and Third Laws to determine which force will push the foot forward. Hint  (why it is difficult to walk on a slippery surface?)

Ticket Out the Door:

Below this lesson plan you will see a link that says “Leave a comment”. Click on this link and answer the two question below. Do not forget to put your name in this format “Samantha B.” Whole first name and the initial of the beginning of your last night. These responses to the ticket out the door will be part of your participation grade.

#1 – What is the number one thing you learned today?

#2 – What was the most confusing thing we covered today?

Homework:

1. Study your Newton notes. You will have a quiz on Wednesday (1-22-2020) at the beginning of class.
2. Finish the Newton Motion Review paper we started in class. Worksheet -> Forces and Newtons Laws Review (Blank)
3. IF you want to get a jump on your work then start tackling this assignment:
