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.
Answer
Brief Explanations:
The amplitude of simple - harmonic motion of a mass - spring system is the maximum displacement from the equilibrium position. Pulling the mass down farther increases this maximum displacement. Changing the length of the spring, mass, or spring stiffness affects the period and frequency of the motion, not the amplitude directly.
Answer:
He could pull the mass down farther.
