Oscillatory Motion: The Concept of the Oscillatory Motion

The video tutorial introduces the concept of oscillatory motion using a simple pendulum experiment. It explains how to set up the pendulum with a pencil, thread, and coin, and describes the pendulum's motion as it swings back and forth. The tutorial highlights the equal displacement in each oscillation and the changes in velocity as the pendulum moves. Finally, it concludes with a clear definition of oscillatory motion, emphasizing the pendulum's movement around its rest position.

What materials are required to perform the oscillatory motion experiment?

• A stick, a rope, and a marble

• A pen, a 50 cm long thread, and a stone

• A ruler, a string, and a ball

• A pencil, a 30 cm long thread, and a coin

What is the primary characteristic of the pendulum's movement?

• It moves in a circular path

• It moves back and forth around its original position

• It moves in a straight line

• It moves randomly

How does the displacement of the pendulum behave during oscillation?

• It varies with each oscillation

• It is equal in every oscillation

• It increases over time

• It decreases over time

What happens to the pendulum's velocity as it passes its original position?

• It stops completely

• It reaches its minimum value

• It remains constant

• It reaches its maximum value

What is the term used to describe the movement of the pendulum around its rest position?

• Oscillatory motion

• Random motion

• Circular motion

• Linear motion
