Oscillations: NEET questions with solutions
NEET uses this chapter for periods of spring-mass systems and simple pendulums, velocity and acceleration at a given displacement, energy sharing between kinetic and potential forms, phase relations, and recognising SHM from a function or force law. Marks are lost by mixing ν with ω, forgetting that energies repeat every T/2, and assuming a pendulum's period depends on the bob's mass.
