Question

Bob of simple pendilum is good example of 1.)oscillatory 2.) periodic motion

Answer 1

Answer:

2. periodic motion

because it moves to and fro with a time interval of = T = 4π√(l/g)

Answer 2

Answer:

1. ocillatory

Explanation:

Pendulum's motion is simple harmonic motion. ... because even at large amplitudes there is restoring force pulling the pendulum toward mean position and its acceleration is directly proportional to the displacement.

A pendulum is a weight suspended from a pivot so that it can swing freely. ... When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period.
