Question

You are holding a rock tied to a string, which is an example of a pendulum. Identify and explain the proper term for each part of the pendulum in this example. Hint: There are three parts. ( Will Mark Brainliest). ​

Answer 1

Explanation:

The rock is called the “bob”, the string is normally called a “mass less rod” and the point where your finger and the string touch is called the “pivot” or “friction less pivot”

It maybe worth noting that we assume:

(i) the rod is in extensible as well as mass less

(ii) the amplitude remains below  $\approx 5^0$

 (iii) the bob is a point mass

(iv) there is no air resistance

(v) gravitational force is constant

(vi) the support / pivot is entirely motionless
