Question

4. Describe Galileo's discovery of a pendulum.​

Answer 1

Because of his mathematical approach to motion, Galileo was intrigued by the back and forth motion of a suspended weight. Galileo's discovery was that the period of swing of a pendulum is independent of its amplitude--the arc of the swing--the isochronism of the pendulum.

Answer 2

Answer:

Galileo's discovery was that the period of swing of a pendulum is independent of its amplitude--the arc of the swing--the isochronism of the pendulum. [1] Now this discovery had important implications for the measurement of time intervals. ... The study of the pendulum, the first harmonic oscillator, date from this period.
