Class 11 Physics — Chapter 14: Oscillations
66 practice questions · 22 Easy · 22 Medium · 22 Hard
Practise Class 11 Physics Chapter 14, "Oscillations", with 66 NCERT-aligned multiple-choice questions. The set is split into 22 Easy, 22 Medium and 22 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams, JEE Main, JEE Advanced and NEET UG.
"Oscillations" is one of the chapters where numerical problem-solving, derivations and conceptual application really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Oscillations, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 11 Physics mastery score. A few sample questions are shown below; sign in free to practise all 66.
Key concepts: Oscillations (Class 11 Physics)
This chapter covers periodic and simple harmonic motion (SHM) — its equations, energy, the simple and spring pendulums, and resonance.
- Simple harmonic motion
- Oscillation where the restoring force is proportional to displacement and directed toward equilibrium (F = −kx).
- SHM equations
- Displacement x = A sin(ωt + φ); velocity and acceleration follow, with a = −ω²x.
- Energy in SHM
- Total energy ½kA² stays constant, continually exchanging between kinetic and potential forms.
- Time periods
- Spring: T = 2π√(m/k); simple pendulum: T = 2π√(L/g).
- Damping & resonance
- Real oscillations lose energy (damping); resonance occurs when the driving frequency matches the natural frequency.
Key formulas — Oscillations
💡 Exam tips for Oscillations
- The hallmark of SHM is a = −ω²x (acceleration proportional to and opposite the displacement).
- At the mean position KE is maximum and PE zero; at the extremes it is the reverse.
Sample questions
In SHM, restoring force is proportional to:
F = −kx.
Period of mass m on spring k:
T = 2π√(m/k).
If x = A sin(ωt), then velocity v =
v = dx/dt = Aω cos(ωt).
