DAY 15

#Goals: SWBAT...

1. define free-fall without using the term, "force"

2. solve 1-D kinematics problems using the UAM equations.

Warm-Up (4min)

1. Give An Example of An Object in Free-Fall
1. If an object is in free-fall, is that an example of UAM?
2. Why does Mr. P use the phrase, "the vacuum that you can breathe"?
3. Define "free-fall" without using the word "force"

CLASSWORK

1. #015A: Notes: Representing Free-Fall with Graphs

a. Draw a p-t graph. Draw a line representing the motion of an object in free-fall

b. hint: does the position change more in the first second, or in the second second?

c. revise if necessary

d. Draw a v-t graph. Draw a line representing the motion of an object in free-fall.

e. hint: does the velocity change more in the first second, more in the second second, or is the velocity change constant?

2. #015B: Practice Problems w/ Free-Fall

- Solve 14 & 16 here: http://www.physicsclassroom.com/Class/1DKin/U1L6d.cfm

- Use GUESS

At Home Learning (HW)

**This weekend, expect to start seeing grades in schoology. Probably not all grades, as this is my b-day weekend, and my daughter's as well.** (I like Coke and Almond Joy ;-)

1. #015B practice problems. If you didn't complete this in class...do it for HW

- use GUESS

- solve # 14 & 16

2. #015C: Tuesday we will attempt more complicated Free Fall problems as we build towards our ramp/cup/ball bearing challenge
