• Practice Kinematics

Mechanical Systems

Draw a picture with all the forces acting upon it.  (F.B.D)

Assign a direction to be positive.  (F.O.R) + usually     preferred  for the direction of acceleration.

Write a relationship for the sum of the forces 

          in the x and y direction.

Substitute and solve for unknown terms

this may need to be done repeatedly

In a system that includes Multiple Bodies:

        write the equation for each body

        write an equation for the combined system

* Note:  If objects are bound, they must share the same                             motion but not necessarly the same force.

EXTRA CREDIT: Whats the difference?

Derive a formula that calculates the distance traveled of a projectile.
When given the range and max height.
Discuss ideas on the blog:
Turn in a card that clearly show all critical ideas
and all math concepts clearly

That is to say if you stretched a string along the objects trajectory what would the length of the string be?

Unit Vectors

• You should have read CH.3
• Test your knowledge
•  Unit Vectors notation
•  FLIPPING physics guy 

•  Vector Lab

Suggested Problems
Assignments
a. Use questions 2, 3, and 4 to discuss properties of vectors. Questions 1 and 5 deal with
vector addition and subtraction. Question 4 deals with the signs of components.
b. Ask students to use graphical representations of vectors to think about problems such as
8 and 10.
18 Lecture Notes: Chapter 3
c. Problems 1, 6, and 10 cover the fundamentals of vector components. Problems 5 and 4
stress the physical meaning of vector components. Some good problems to test understanding
of analytic vector addition and subtraction are 15, 16, 20, and 24.
d. Unit vectors are used in problems 12, 13, 18, and 20.

DAY # 3 Graphical Analysis of Motion

Graphical Analysis of Motion

• refrain from using the word it

2016 AP PROBLEM #1

We discussed in 2 possibilities for the A vs. F graph.

• Make a choice about which one you agree with and why?
• Sketch a continuation of the graph after the string is cut until it stops?
• are there any inconsistencies with the graph and the motion of the object?
• Explain?
