FAQs on Simple Harmonic Motion (SHM) Solved Examples for JEE

Question 1

1. What is Simple Harmonic Motion (SHM)?

Accepted Answer

Ans. Simple Harmonic Motion (SHM) is a type of periodic motion where the restoring force is directly proportional to the displacement from the equilibrium position and acts in the opposite direction. It can be represented by a sine or cosine function.

Question 2

2. How is the period of a simple harmonic motion related to its frequency?

Accepted Answer

Ans. The period of a simple harmonic motion is the time taken for one complete cycle, while the frequency is the number of cycles per unit time. They are inversely proportional to each other, meaning that as the period increases, the frequency decreases, and vice versa.

Question 3

3. What is the relationship between the amplitude and energy of a simple harmonic oscillator?

Accepted Answer

Ans. The amplitude of a simple harmonic oscillator is directly proportional to its energy. As the amplitude increases, the energy stored in the oscillator also increases. This relationship can be observed in the oscillation of a pendulum or a mass-spring system.

Question 4

4. How does the mass of an object affect its period in simple harmonic motion?

Accepted Answer

Ans. The period of simple harmonic motion is not affected by the mass of the object. Whether the object is heavy or light, the period remains the same as long as the restoring force is proportional to the displacement. The mass does, however, affect the amplitude of the oscillation.

Question 5

5. Can the displacement in simple harmonic motion be greater than the amplitude?

Accepted Answer

Ans. No, the displacement in simple harmonic motion cannot be greater than the amplitude. The amplitude is the maximum displacement from the equilibrium position, and the object oscillates back and forth within this range. The displacement can vary from zero to the amplitude value.
