What would driving a car be like if it had no suspension system?
Spring and Mass Systems • Define simple harmonic motion. • periodic • restoring force magnitude linear with respect to displacement • restoring force direction always toward the equilibrium position Notes: • If friction = 0, the displacement is symmetrical about the equilibrium position. • equilibrium position is location where total force = 0. • restoring force is actually the sum of all forces • Give an example of motion that is periodic but not simple harmonic. The orbit of planets • Draw the energy diagram for a spring in simple harmonic motion (p. 232), define the equilibrium position and describe location along the masses path of: • max and min velocity–at equilibrium position • max and min acceleration–at extremes • max and min restoring force–at extremes • max and min kinetic energy–at equilibrium position • max and min spring potential energy–at extremes Note: the above does not change with the orientation of the spring. In other words, it does not matter if the spring is
