Week 6:  12 October to 16 October 2020

11 October 2020:

No Class:  Columbus Day holiday.

12 October 2019:

In Class:  Motion in two dimensions.

Expectations:  Students will be able to solve problems with motion in two dimensions using vertical components.

Due:  Pages 1:152-153 (126 – 134).

Homework:  Pages 1:153-156 (135 – 153).

13 October 2020:

In Class:  Projectiles Fired at an Angle.

  • Ay = A sin θ
    Ax = A cos θ
  • A = Any vector
    Ay = Vertical component of A
    Ax = Horizontal component of A
    θ = Angle from A to horizontal
  • Right triangle

    • Expectations:  Students will resolve a vector into its vertical and horizontal components and solve problems to find range, altitude, and time in the air for projectiles fired at different angles to the ground.

    Due:  Pages 1:153-156 (135 – 153).

    Homework:  Pages 1:155-156 (154 – 165).

    14 October 2020:

    No Class:  Physics does not meet on Thursday.

    15 October 2020:

    In Class:  Uniform Circular Motion.

  • ac =
  •  v 2
      r  
  • ac = centripetal acceleration
    v = velocity or speed
    r = radius or distance between centers

    • Expectations:  Students will be able to solve problems using the circular motion equation.

    Lab 3:
    Data collection and analysis of Speeding Cars Lab.

    Expectations:  Students will be able to use a spreadsheet to analyze distance and time data and to create graphs to find velocity.

    Due:  Pages 1:155-156 (154 – 165).

    Homework:  Pages 1:155-161 (166 – 196).

    Note:  quarter ends 12 November 2021.
