Frequency and Period of SHM

AP Physics 1· difficulty 2/5

The amplitude of a spring-mass oscillator is doubled (ideal spring, no damping). What happens to the period?

  • A

    It quadruples.

  • B

    It stays the same.

  • C

    It halves.

  • D

    It doubles.

Explanation

For SHM, period is independent of amplitude: T=2πm/kT = 2\pi\sqrt{m/k} — no AA dependence.
