Unit 1: Newtonian Odds & Ends: Torque and Simple Harmonic Motion (SHM)
By the end of this unit a successful student should be able to:
- Define torque in terms of forces and lever arm distances
- Solve torque equilibrium problems (AP PhysB: IE2)
- Recognize examples of simple harmonic motion (MSTE: Phys 4.1)
- Understand Simple Harmonic Motion (dynamics and energy relationships) for masses on springs, pendula and other oscillations (AP PhysB: IF)
- Recognize the relationship between period of oscillation and frequency
- For a given example of SHM identify where the maxima and minima of speeds, displacement, and acceleration will occur
- For both a spring describe and solve problems involving the mechanical energy of the system.
- Express the mechanical energy and velocity of a spring SHM in terms of its amplitude
- Relate and be able to derive the relationship between the period of a spring oscillator, and the mass of the oscillator.
- Express position, velocity and acceleration as a function of time for a simple harmonic oscillator (SHO).
- Show the approximate relationship between period and pendulum length for small oscillations.
