Warm Up:  Get out yesterday's dot product notes.  What is the dot porduct and angle of the vectors (-3i+5j) and (2i+-2j).

9/26

Objective:  SWBAT determine the angle between two vectors using dot products.


Warm Up:  Find the dot product of a (dot) b if a=(3i-7j+4k) and b=(-7i+3j+2k)

9/23

Objective:  SWBAT find the resultant and direction of a vector using unit vector notation.

Warm Up:  Why do we use unit vectors in physics?

9/22

Objective:  SWBAT uderstand how to find the resultant of two or more vectors and how to resolve vectors in 2 and 3 dimensions into their components.

Warm Up:  A car moves 85 m at 79o then moves 63 m at 280o then moves 150 m at 45o.  What is the distance traveled and the displacement of the car?

9/20

Objective:  SWBAT determine the velocity and acceleration of a particle using calculus to find the first and second derrivatives of it's displacement equation.

Warm Up:  Pick up one hand out.  Solve the problem on the board.

9/18

Objective:  SWBAT perforn a lab on a cart that has constant acceleration.

Warm UP: Turn in your Ch 2 HW.  Pick up one lab handout.  Pre-read the lab.

9/16

Objective:  SWBAT solve a complicated problem involving forces, changes in momentum, and kinematics.

Warm Up:  Pick up two handouts.  Find your group mates and find a spot in the classroom to work together.  Draw the Free Body Diagram for part a of the problem.

Homework due date moved to Monday :)

9/15

Objective:  SWBAT understand how to take a simple derrivative of position with respect to time.

Warm Up:  Pick up your last test. When should you leave a question on a FRQ blank?

9/14

Objective:  SWBAT mimic the motion (by walking) shown on a velocity vs time graph.

Warm Up:  Back into our groups for graph matching.  Just open an v vs t graph and try to match the graph on the board.

9/13

Objective:  SWBAT match the motion depicted on a graph when walking in front of a motion sensor.

Warm Up:  Turn in your Diluting Gravity Lab.  When is it acceptable to vary two things at the same time during an experiment?

9/7

Objective:  SWBAT perform a lab to determine g in J-208.

Warm Up:  Turn in your Flag Pole Lab
Get out your lab handout from yesterday.
What value of g would your expect to get in this classsroom?  What are the two methods that we are going to use to determine it?

Test Friday on Ch 1.

9/6

Objective:  SWBAT demonstrate their knowledge of the summer assignment on a quiz

Warm Up:  Pick up two lab handouts and staple together.
Get out a pencil and calculator.

Flag Pole lab due tomorrow.
Test on Ch 1 Friday.

9/2

Objective:  SWBAT review for the quiz.

Warm Up:  Turn in your homework.  Define Accuracy and Precision in a measurement.

9/1

Objective:  SWBAT determine the height of the flag pole experimentally.

Warm Up:  So, what is the thickness of a single page of your book?

Note:  Quiz tomorrow on the summer assignment and error in measurements.
