Question

5. What is the speed of the bob at the bottom of a swing if its amplitude is 60Degrees and the length of its string is 20cm. Assume no air friction and g = 10m/s2.

Answer 1

Explanation:

A simple pendulum consists of a point mass suspended on a string or wire that has negligible mass. If the pendulum weight or bob is pulled to a relatively small angle from the vertical and let go, it will swing back and forth at a regular period and frequency. These requirements allow for the equations to be relatively simple and are called simple harmonic motion.

If the bob is larger, the wire has mass, or the angle is larger, it is called a physical pendulum with complex equations of motion.

Although damping effects from air resistance and friction are a factor, they are considered negligible for the basic equations concerning the frequency or period of the pendulum.
