Read these lines from your NCERT book twice: NEET has built questions on each of them more than once.

SHM needs acceleration = -(positive constant) × x . sin ωt ± cos ωt is SHM, but sin ²ωt and sin ωt + cos 2ωt are not, and e^(-ωt) is not even periodic.

Use v = ω√(A² − x²) and vₘₐₓ = ωA; the time from the mean to A/2 is T/12 , found from the reference circle.

For a spring, T = 2π√(m/k) , so T∝√m. A spring cut into 4 equal pieces has k → 4k , and in series 1/k = 1/k₁ + 1/k₂.

Total energy (1/2)kA² stays constant, and U/E = (x/A)² . At x = A/2 the PE is E/4 and the KE is 3E/4 .

AIPMT 1993AIPMT 1995AIPMT 2003

If the displacement has frequency n, KE and PE oscillate at 2n , while the total energy is constant . The KE is maximum when the PE is zero.

AIPMT 2002AIPMT 2007NEET 2021

A simple pendulum has T = 2π√(L/g) , so a small increase in L of 2% gives about 1% more T. A rocket accelerating upward makes g_(eff) larger and T smaller .

Free NCERT notes for Oscillations

Periodic motion, simple harmonic motion (SHM), the energy of an oscillator, and the spring and pendulum systems. NEET usually asks a direct question from here (a time period, a speed at some x, or an energy ratio), and the same ideas carry straight into Waves.
