FAQs on Periodic Motion: Small Oscillations, Normal Modes Video Lecture - CSIR NET Crash Course for Physical Science - CSIR NET Physical Science

1. What is periodic motion?
Ans. Periodic motion is a type of motion that repeats at regular intervals. It involves a back-and-forth movement around a central point or equilibrium position.
2. What are small oscillations in periodic motion?
Ans. Small oscillations refer to motions where the displacement from equilibrium is small. In the context of periodic motion, small oscillations occur when the system is perturbed slightly and returns to its original position.
3. What are normal modes in periodic motion?
Ans. Normal modes are specific patterns of motion in a system that oscillates at a single frequency. Each normal mode corresponds to a unique oscillation pattern with a specific frequency.
4. How are normal modes related to small oscillations in periodic motion?
Ans. In the case of small oscillations, the system can be described by its normal modes. These normal modes provide a convenient way to analyze and understand the motion of the system when it is perturbed from equilibrium.
5. How can normal modes be calculated in the context of periodic motion?
Ans. Normal modes can be calculated by solving the equations of motion for the system and finding the frequencies at which the system oscillates. These frequencies correspond to the natural frequencies of the system in its normal modes.
