Ph 213 Chapter : Motion of a pendulum.pdf

what are approximate simple harmonic motion and exact simple harmonic motion and why exactly simple harmonic motion and exact simple harmonic motion and why exactly simple harmonic motions are rare?

Current in a conductor is normally due to:

a) the drift motion of both electrons and positrons

b) the drift motion of the conduction electrons due to electric fields

c) the collective motion of all electrons in the conductor

d) the thermal motion of the conduction electrons

e) the drift motion of both electrons and protons

Describe four different situations that can result in motion perception. Which of these situations involves real motion, and which involve illusions of motion?
