The amplitude of an oscillator is doubled. Which of the following statements are true (select all that apply)?

The frequency is doubled

The energy is unchanged

The frequency is unchanged

The velocity at the equilibrium point is doubled

The energy is doubled.

The frequency is doubled

The energy is unchanged

The frequency is unchanged

The velocity at the equilibrium point is doubled

The energy is doubled.

Explanation / Answer

as energy = 1/2 * k * A^2

for double amplirude,

energy is 4 times

and veloctiy = Aw , for double amplitude , velocity is double,

The velocity at the equilibrium point is doubled
