In SHM, which quantity is maximized when the particle’s acceleration is at its peak?
**Energy distribution** shows maximum kinetic at equilibrium and maximum potential at extremes, sum constant. This relation enables calculation of amplitude, velocity at any displacement via v = ±√(2(E-U)/m), and understanding of energy storage in oscillating system for NEET problems. Acceleration peaks at aₘₐₓ = ω² A when x = ± A (extreme positions), where potential energy ( U = (1/2) k A² ) is maximum. Applying x = A cos(ωt + φ), v = -ωA sin(ωt + φ), a = -ω²x and E = ½kA² = ½mω²A², result Potential energy follows, reflecting SHM dependence on amplitude A, ω and system parameters.
