West Bengal Joint Entrance Examination (WBJEE) is a state level common entrance test organized by West Bengal Joint Entrance Examinations Board for admission to the Undergraduate Level Engineering and Medical Courses through a common entrance test in the State of West Bengal. Students can easily crack WBJEE Examination as the difficulty level of this examination is not too high. We bring to you chapter notes of chapter Simple Harmonic Motion including all important topics like **simple harmonic motion, acceleration in simple harmonic motion, velocity in simple harmonic motion, kinetic energy in simple harmonic motion, potential energy in simple harmonic motion** etc. These notes will help all WBJEE aspirants to revise all important topics of chapter Simple Harmonic Motion in less time before the examination.

**Important Questions and Preparation Tips – Rotational Motion**

**Some previous years solved questions are given below:**

**Question 1:**

When a particle executing SHM oscillates with a frequency *ν*, then the kinetic energy of the particle

(A) changes periodically with a frequency of *ν*

(B) changes periodically with a frequency of 2*ν*

(C) changes periodically with a frequency of *ν*/2

(D) remains constant

**Solution 1:**

When a particle executing SHM oscillates with a frequency ν, then the kinetic energy of the particle changes periodically with a frequency of 2*ν*.

Hence, the correct option is (B).
