Question

attempt a) Why is the motion of pendulum swinging in a clock called harmonic mo b) Explain the cause of damping​

Answer 1

Answer: a)A pendulum undergoes simple harmonic motion. It swings to and fro about its mean position where the string and the bob undergo the motion. These movements of pendulums are called oscillations, which show simple harmonic motion.

b)Damping in Physics is the restraining of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by the dissipation of energy. Friction is an example of mechanical damping. It arises chiefly from the electrostatic forces of attraction between the sliding surfaces and converts kinetic energy into heat.
