Trevor places a mass on a spring. When he releases it, the mass and spring move in simple harmonic motion.

How could Trevor increase the amplitude of the motion?

He could use a longer spring.
He could use a smaller mass.
He could use a stiffer spring.
He could pull the mass down farther.

Respuesta :

The answer is D, He could pull the mass down further.

The correct answer is D He could pull the mass down farther.

Amplitude, is the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. So to increase the amplitude the spring should be pulled down further which can increase the amplitude.
