Introduction to Oscillation for NEET

Oscillation is a repetitive motion of a body around an equilibrium position. A pendulum swinging back and forth, a spring moving up and down, or even the vibrations of a tuning fork are examples of oscillatory motion.

In the NEET physics syllabus, questions based on oscillation are common because they test both theoretical understanding and problem-solving ability. Therefore, mastering oscillation can give you a clear advantage in the physics section of NEET.

Importance of Oscillation in NEET

Oscillation holds significant weightage in NEET physics, contributing to around 5–7% of the total physics questions. Questions related to oscillation are often conceptual and calculation-based, requiring a deep understanding of formulas and their applications.

Oscillation-based questions are designed to test:
✅ Understanding of SHM and other oscillation types
✅ Application of key formulas
✅ Ability to solve time-based problems
✅ Conceptual understanding of damping and resonance

Common Questions from Oscillation in NEET

In NEET, the following types of questions from oscillation are frequently asked:

By practicing MCQs, you can familiarize yourself with the typical question patterns and improve your accuracy and speed in solving them.


Key Concepts of Oscillation

To tackle oscillation-based MCQs in NEET, you need to have a strong grasp of the fundamental concepts. Let’s break down the core ideas related to oscillation.

Types of Oscillations

  1. Free Oscillation
    • Occurs when a system oscillates without any external force after being displaced from equilibrium.
    • Example: A simple pendulum swinging freely.
  2. Damped Oscillation
    • In real-life scenarios, friction and resistance reduce the amplitude of oscillation over time, causing the oscillation to eventually stop.
    • Example: A pendulum in water slows down due to water resistance.
  3. Forced Oscillation
    • When an external periodic force is applied to a system, it causes continuous oscillation.
    • Example: A swing being pushed periodically.
  4. Resonance
    • When the frequency of the applied external force matches the natural frequency of the system, the amplitude of oscillation increases significantly.
    • Example: A glass shattering when exposed to a sound wave at its resonant frequency.

Simple Harmonic Motion (SHM)

Simple Harmonic Motion is a type of oscillation where the restoring force is directly proportional to the displacement and acts in the opposite direction.

Characteristics of SHM:

F=−kxF = -kxF=−kx

where:

Equation of SHM:

The general equation of SHM is: x(t)=Asin⁡(ωt+ϕ)x(t) = A \sin(\omega t + \phi)x(t)=Asin(ωt+ϕ)

where:


Damped and Forced Oscillations

  1. Damped Oscillation:
    • Amplitude decreases over time due to energy loss.
    • The equation of damped oscillation:

x(t)=Ae−btcos⁡(ωt+ϕ)x(t) = A e^{-bt} \cos(\omega t + \phi)x(t)=Ae−btcos(ωt+ϕ)

where:

  1. Forced Oscillation:
    • External force applied to maintain oscillation.
    • Equation of forced oscillation:

x(t)=Acos⁡(ωt−ϕ)x(t) = A \cos(\omega t – \phi)x(t)=Acos(ωt−ϕ)


Formulas and Key Equations in Oscillation

Memorizing and understanding key formulas is essential for solving oscillation MCQs efficiently. Here’s a summary of the most important ones:

Solution:
Using the formula: T=2πmkT = 2\pi \sqrt{\frac{m}{k}}T=2πkm​​ T=2π0.5100=2π0.005≈0.44 sT = 2\pi \sqrt{\frac{0.5}{100}} = 2\pi \sqrt{0.005} \approx 0.44 \, sT=2π1000.5​​=2π0.005​≈0.44s

Answer: 0.44 s


Question 2

A simple pendulum with a length of 1 m is placed in a room where the gravitational acceleration is 9.8 m/s². What is the time period?

Solution:
Using the formula: T=2πlgT = 2\pi \sqrt{\frac{l}{g}}T=2πgl​​ T=2π19.8≈2.006 sT = 2\pi \sqrt{\frac{1}{9.8}} \approx 2.006 \, sT=2π9.81​​≈2.006s

Answer: 2.006 s


Question 3

Solution: F=−kxF = -kxF=−kx F=−50×0.1=−5 NF = -50 \times 0.1 = -5 \, NF=−50×0.1=−5N

Answer: -5 N

Oscillation MCQs for NEET – Intermediate Level

Once you’ve built a solid foundation with basic-level MCQs, it’s time to move on to intermediate-level questions. These questions are designed to test your conceptual understanding and ability to apply formulas in slightly more complex scenarios.

Question 1

A mass of 2 kg is attached to a spring of spring constant 200 N/m. The system is displaced by 0.1 m and released from rest. Find the maximum velocity of the mass.

Solution:
The maximum velocity in SHM is given by: vmax=ωAv_{max} = \omega Avmax​=ωA

where: ω=km=2002=100=10 rad/s\omega = \sqrt{\frac{k}{m}} = \sqrt{\frac{200}{2}} = \sqrt{100} = 10 \, \text{rad/s}ω=mk​​=2200​​=100​=10rad/s

Therefore, vmax=10×0.1=1 m/sv_{max} = 10 \times 0.1 = 1 \, \text{m/s}vmax​=10×0.1=1m/s

Answer: 1 m/s


Question 2

A simple pendulum with a length of 0.5 m is oscillating with a time period of 1.41 s. Find the value of gravitational acceleration.

Solution:
The time period of a pendulum is: T=2πlgT = 2\pi \sqrt{\frac{l}{g}}T=2πgl​​

Rearranging for ggg: g=4π2lT2g = \frac{4\pi^2 l}{T^2}g=T24π2l​

Substituting values: g=4×3.142×0.5(1.41)2g = \frac{4 \times 3.14^2 \times 0.5}{(1.41)^2}g=(1.41)24×3.142×0.5​ g=4×9.8596×0.51.9881g = \frac{4 \times 9.8596 \times 0.5}{1.9881}g=1.98814×9.8596×0.5​ g≈9.86 m/s2g \approx 9.86 \, \text{m/s}^2g≈9.86m/s2

Answer: 9.86 m/s²


Question 3

An object undergoing SHM has an amplitude of 0.2 m and a period of 2 s. Find the maximum acceleration of the object.

Solution:
Maximum acceleration in SHM is: amax=ω2Aa_{max} = \omega^2 Aamax​=ω2A

where: ω=2πT=2π2=π rad/s\omega = \frac{2\pi}{T} = \frac{2\pi}{2} = \pi \, \text{rad/s}ω=T2π​=22π​=πrad/s

Therefore, amax=(π)2×0.2≈9.86×0.2=1.97 m/s2a_{max} = (\pi)^2 \times 0.2 \approx 9.86 \times 0.2 = 1.97 \, \text{m/s}^2amax​=(π)2×0.2≈9.86×0.2=1.97m/s2

Answer: 1.97 m/s²


Oscillation MCQs for NEET – Advanced Level

Solution:
The total energy in SHM is: E=12kA2E = \frac{1}{2} k A^2E=21​kA2

where: k=150 N/m, A=0.05 mk = 150 \, \text{N/m}, \, A = 0.05 \, \text{m}k=150N/m,A=0.05m E=12×150×(0.05)2E = \frac{1}{2} \times 150 \times (0.05)^2E=21​×150×(0.05)2 E=75×0.0025=0.1875 JE = 75 \times 0.0025 = 0.1875 \, \text{J}E=75×0.0025=0.1875J

Rearranging for kkk: k=4π2mT2k = \frac{4\pi^2 m}{T^2}k=T24π2m​

Substituting values: k=4×(3.14)2×432k = \frac{4 \times (3.14)^2 \times 4}{3^2}k=324×(3.14)2×4​ k=4×9.8596×49k = \frac{4 \times 9.8596 \times 4}{9}k=94×9.8596×4​ k≈17.53 N/mk \approx 17.53 \, \text{N/m}k≈17.53N/m
