10/22

Objective:  SWBAT relate force with the motion of an object.

Warm Up:  Get out your netbook,open edmodo, and start the sim.

Note that the you will be using two different sims for this assignment- Moving Man, and Forces and Motion.  To get to the sims within the pHet site, click on Physics on the far left column.  The Physics sims are listed in alphabetical order.

9/25

Objective:  SWBAT explore vectors using a riverboat simulation

Warm Up:  Get out your netbook, log on to edmodo and complete the river boat sim posted in edmodo.  Copy and paste the questions into a word doc, answer the questions and resubmit to me as a post in edmodo.

9/20

Objective:  SWBAT manipulate unit vectors including addition, cross products and dot products.

Warm UP:  Today is a work day.  Finish your sim, or take notes from the power point, or work on the problems assigned.  NO food or drink around the netbooks.

9/19

Objective :  SWBAT review the basics of projectile motion.

Warm Up:  Get out your netbook and log into edmodo (unless your netbook number is listed on the board).  If your netbook number is listed on the board then it won't run the sim because it doesn't have Flash installed.  Use one of the regular student computers instead, until we fix the Flash problem.  Complete the U of Colorado (PHeT) sim activity.  NO FOOD OR DRINKS MAY BE OUT WHEN YOU ARE USING THE NETBOOKS.

Note:  The average on the M.C. section of the test was 73%.  It is obvious from the grades that you either knew the material or you didn't.   I have not graded the FRQ yet.

9/17

Objective:  SWBAT review for tomorrow's test.

Warm Up:  Get out your Example Problem packet.  Do number 3.

9/11

Yesterday we did a lab to determine d, v and a of a cart given a constant acceleration from a fan.

Today we worked in small groups learning how to differentiate simple equations using some calculus short cuts.

9/5

Objective :  SWBAT review the basics of kinematics.

Warm Up:  What are the 4 basic kinematic equations that we used last year (not the one that define d, v, and a)?

8/28

Objective:  SWBAT determine the value of g in the classroom using two different methods.

Warm Up:  Pick up a lab packet and preread the introduction, equipment, and experimental procedures.

8/28

Objective:  SWBAT take a quiz on the AP summer assignment.

Warm Up:  List some causes of error when you take measurements.  Then come up with ways to minimize them.

8/27

Objective:  SWBAT understand how to estimate answers and how to write a formal lab writeup

Warm Up:  Pick up one handout.  How many breathes would the average dog take in its lifetime?

8/24

Objective:  SWBAT review measurements and error.

Warm Up:  Pick up two handouts.  How are absolute and relative error related?

8/23

Objective: SWBAT understand the importance of units, dimensional analysis and estimating error in science.

Warm Up: Pick up one handout, one safety test, and your scantron. On a separate sheet of paper copy the questions you got wrong AND give the correct answer AND the reason for the correct answer. Staple your corrections to your scantron.

If your scantron is not there, please see me.

8/21

Objective: SWBAT review safety procedures in the lab and take the safety test.

Warm Up: Place signed papers in separate piles on the back table in the class.

Find a partner and determine one thing that you should NOT do in a science class during a lab.

8/21

Welcome back to another school year!

Objective:  SWBAT familiarize themselves with the AP Physics C course, what we will be learning this year, and what is expected of them this year.

Warm Up:  Pick up 9 handouts.  (Yes, 9 handouts!!) Have a seat where you will learn best.

Quiz: http://www.polleverywhere.com/my/polls#!/my/polls  (really it's just a poll so don't panic)

Homework: 
1)  Fill out your paperwork, get parent signatures, and turn in tomorrow.
2)  Log on to Edmodo (www.edmodo.com), create an account if you don't already have one and do the short assignment.
3)  Read the safety contract.  Tomorrow you will take the Safety test.

5/1

Objective:  SWBAT determine the forces on an object in equilibrium.


Warm Up: Draw a free body diagram of the top pulley in this picture.

4/26

A 10.0 kg box is pushed from the top of an incline and travels down the incline with an initial speed of 5.00 m/s.  The incline is 4.00 m long and the angle of the incline is 37.0 degrees.  The coefficient of friction between the box and the incline is 0.400.  Determine the a) loss of potential energy and b) work done by friction.  c) Use the work-energy theorem to determine the velocity of the box at the bottom of the incline.

4/25

Objective:  SWBAT determine the limit that defines the terminal velocity of an object that encounters velocity dependent resistive forces.


Warm Up:  You are 1000 m high in an air balloon and you drop your physics book overboard.  Sketch the d vs t, v vs t and a vs t graphs for the book (assume that at some point it reaches terminal velocity).

4/24

Objective:  SWBAT determine the force on an object (Review of Forces)


Warm Up:  A 2 kg mass is pushed 0.5 m into a spring with spring constant 200 N/m on a frictionless horizontal surface.  Upon release, the mass travel across the surface until it encounters a rough incline.  The mass moves up the incline and stops at a height of 1 m above the horizontal surface.
a.  How much work must be done to compress the spring initially?
b.  What is the speed of the mass at the base of the incline.
c.  How much work was done by friction on the incline?

Physics: Retarding and Drag Forces

4/20

Objective:  SWBAT calculate projectile motion.

Warm Up:  Pick up a half sheet of paper.  Place your answer to the warm up on the paper.  You must do your own work. You have 4 minutes.


A projectile is fired with an intial speed of 113 m/s at an angle of 60 degrees above the horizontal from the top of a cliff 49 m high.  Determine the time to reach maximum height and the total time of flight.
