Week 11:  15 November to 19 November 2021

15 November 2021:

In Class:  Springs and Hooke's Law:

  • Fs = kx
  • Fs = force on a spring
    k = spring constant
    x = change in spring length from the equilibrium position

    • Expectations:  Students will be able to solve spring constant problems.

    Due:  Pages 2:51-53 (26 – 31).

    Homework:  Pages 2:53-55 (32 – 43).

    16 November 2021:

    In Class:  Springs and Potential Energy:

  • PEs = ½kx2
  • PEs = potential energy stored in a spring
    k = spring constant
    x = change in spring length from the equilibrium position

    • Expectations:  Students will be able to solve spring potential energy problems.

    Due:  Pages 2:53-55 (32 – 43).

    Homework:  Pages 2:55-56 (44 – 52).

    17 November 2021:

    In Class:  Kinetic Energy:

  • KE = ½mv2
  • KE = kinetic energy
    m = mass
    v = velocity or speed

    • Expectations:  Students will be able to solve kinetic energy problems.

    Due:  Pages 2:55-56 (44 – 52).
