Regents Physics Monday 9/18 Grab a protractor Vectors Intro. (Sect. I – III) MR. MELLON IS OUT TODAY, BUT WATCH THE VIDEOS FOR THE SECTIONS ABOVE Homework/Announcements: None Quiz (short) on Friday based on Unit 1A: Vectors

Regents Physics Tuesday 9/19 Go over notes (Sect. I – III) Vector Component (Sect. IV) Begin Vector Scale Diagrams (Sect. V) Homework/Announcements: Finish pg. 6 of Work Packet Quiz (short) on FRIDAY based on Unit 1A: Vectors

Regents Physics Wednesday 9/20 Grab a protractor Starter/go over HW Vector Scale Diagrams (Sect. V) Pg. 7 of Work Packet Homework/Announcements: None Quiz (short) on FRIDAY based on Unit 1A: Vectors

Starter A person walks 5.00 m @ 90.0 degrees then 8.00 m @ 0.00 degrees. Mathematically determine the resultant (magnitude and direction (in degrees)) of the two vectors. Using the head-to-tail method, sketch the resultant and equilibrant of the two vectors. Determine the horizontal (x) and vertical (y) components for a vector of 25 m/s at 35 degrees from the horizontal. 9.43 m at 32. 0 degrees from the x-axis Ax = 20.5 m/s, Ay = 14.3 m/s

Regents Physics Thursday 9/21 Grab a protractor Starter/go over HW Finish Pg. 7 of Work Packet Begin Unit 2 – Kinematics (Distance vs. Displacement) Homework/Announcements: STUDY FOR TOMORROW’S QUIZ Quiz (short) TOMORROW based on Unit 1A: Vectors

Starter Complete on the back of the WP Create a scaled vector diagram for the vectors below to determine the resultant (both magnitude and direction). Vector 1: 10 N at 180 degrees Vector 2: 8 N at 90 degrees Vector 3: 6 N at 0 degrees B) Then mathematically find the magnitude and direction (in degrees) of the resultant. These numbers should be close with what you got from question A. C) Determine the magnitude and direction of the equilibrant 8.94 N at 117 degrees from the x-axis 8.94 N at 297 degrees from the x-axis
