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?

The amplitude is the greatest distance the mass moves from its equilibrium position. Pulling the mass farther down before releasing it gives it a greater initial displacement, so it oscillates with a larger amplitude. Changing the spring’s stiffness, length, or the mass can affect other features of the motion, but does not directly increase the amplitude in the way described.
