Note: We will only have 1/2 of class time due to college fair that starts at 8:30. Assignment Due today: Ch3 Check Concepts p 41 #1-19 odd.

Today: Be able to give examples and explain the importance of Newton's 1st Law of Motion. Classroom Demo: Eggs. Suspended mass. Define Terms: Friction, Inertia, Newton's 1st Law, kilogram, mass, weight, newton.

What video : @Newton's First Law

HW: Write a working definition of key terms, p 40.

October 11
Over Arching Question: How does Newton's 1st Law apply to objects in equilibrium?

3.5 Mass: A measure of inertia. Differentiate between mass and weight. What is your mass in kg and weight in N? 3.6 The moving Earth. Demo Cart. The moving Earth.

Complete p 42, #21-55 odd, Due end of class.

Quiz on Newton's 1st Law.

October 16
Questions we will investigate in this unit. How can you tell if something is moving. How fast are you spinning with the rotation of the earth? With the rotation around the sun? How do you determine an objects speed? What are its units and base units in physics? Speed vs. Velocity? What does it mean to accelerate?

Read and take notes on Ch 4. To be collected. Emphasis on Section 4.1 and 4.2 Motion is relative and speed.

Discover Activity on page 46. Powerpoint slides presentation on Ch 4.

October 18
Engage: Free Fall video from 24 miles above the earth

What is the difference between speed and velocity? What does it mean to accelerate. Be sure to be able to distinguish between velocity and acceleration. Be able to define each concept.

p 62 Questions 1-6, p64 #26-30 & #58 Define Key terms p 61

Background: Determine one's reaction time is especially critical in emergency response situations. It enables one understand why maintaining a safe distance while driving and other quick response situations is important. Today we will look at what our response time is by using a known rate of acceleration(gravity) to determine our personal reaction time. IS it the same for everyone?

Engage: determine one's reaction time by dropping a ruler. See p 67 #59

Relate free fall with acceleration and describe what it means to in free fall. Reference back to free fall video Felix Baugardner and opening exercise on Tue Oct 16. Determine the speed and displacement at any point in free fall or accelerated motion. Sections 4.5 and 4.6 of text.

Complete Concept development pages 9-17. and/or below problems p62 #7-9, 20-21,31-36 based on concepts p 62 #10-15, 22-24, 37-41 concepts.

October 23
Objective: Apply concepts of speed, velocity, acceleration and free fall. Why: To develop critical thinking skills necessary to analyze any problem and better predict motion of an object. How: By physically being a part of the motion and measuring personal movement at different rates in forward and backward motion. Then using technology to try to match graphs of motion.

Physics 500 Lab activity p 19 and 20 and/or displacement activity with graphing.

p 66 #42-57. additional wksht problems?

Complete a traffic study investigation to determine if the traffic is moving too fast under the convention center. Why: Obtain a better visual understanding of speed and acceleration How: Measure distance and time for vehicles moving at fairly constant speed and accelerating from rest at a stop light.

November 1

Traffic Study Report Due. Describe free fall due to gravity. Determine reaction time. Apply linear motion concepts to solving problems. how: find individual reaction time with ruler and knowing acceleration due to gravity. Text book problems. Why: Develop problem solving skills and critical thinking.

p 62#1-15, 23,24, 26-41 odd due at end of class. Hw: Create an outline of Ch 4.
