Swinging from side to side, like a pendulum in a clock.

Oscillatory motions are a type of periodic motion.

 A pendulum is a good example for an oscillatory motion. In the simple pendulum, the bob oscillates to and fro over the middle equilibrium point. 



The period of such a device can be made longer by increasing its length, as measured from the point of suspension to the middle of the bob.

A change in the mass of the bob, however, does not affect the period, provided the length is not thereby affected. 

The period, on the other hand, is influenced by the position of the pendulum in relation to Earth. Because the strength of Earth’s gravitational field is not uniform everywhere, a given pendulum swings faster, and thus has a shorter period, at low altitudes and at Earth’s poles than it has longer period at high altitudes.



We have our e-books published on Amazon for Grade 3 and Grade 4. The books serve as an important guide for Science Olympiads organized by SOF, Silverzone, Unified Council and others. Books are designed to help students understand key science concepts.

The key highlights of the book are:

·      Well explained topics

·      Use of diagrams and images for students to visualize

·      Test exercise after each chapter for self-assessment and evaluation

·      Interesting facts sections spread across the book

Here are the links:
