Week 8:  24 October to 28 October 2022

24 October 2022:

free body diagram

In Class:  Forces on a Ramp (free body diagrams).

Expectations:  Students will resolve and solve friction and free body diagram problems involving ramps.

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.

Homework:  Pages 1:165-167 (228 – 236).

25 October 2022:

In Class:  Momentum:

  • p = m v
  • p = momentum
    m = mass
    v = velocity or speed

    • and Impulse:

  • J = Fnet t = Δp
  • J = impulse
    Fnet = net force
    t = time
    Δ = change
    p = momentum

    • Expectations:  Students will solve momentum and impulse problems.

    Due:  Pages 1:165-167 (228 – 236).

    Homework:  Pages 1:167-169 (237 – 252).

    26 October 2022:

    In Class:  Kinematics Exam (Chapter 1, sections 1 – 7).

    27 October 2022:

    No Class:  Physics does not meet on Thursday.

    28 October 2022:

    In Class:  Conservation of Momentum:

  • pbefore = pafter
  • pbefore = momemtum before
    pafter = momentum after

    • Expectations:  Students will solve conservation of momentum problems.

    Due:  Pages 1:167-169 (237 – 252).

    Homework:  Pages 1:169-171 (253 – 259).
