STEM student for a day Quiz

What is the most important thing needed for an object to oscillate with simple harmonic motion?

• It needs to be attached to a spring or other elastic object.

• It needs to be acted on by a net force that is proportional to object's displacement from equilibrium.

• It needs to be acted on by a balanced force that is proportional to object's displacement from equilibrium.

• It needs to be acted on by a driving force which is sinusoidal.

The picture shows a position of simple harmonic oscillator as a function of time.

• A = 1.5 cm

• A = 2.0 cm

• A = 4.0 cm

• A = 8.0 cm

The picture shows position of a simple harmonic oscillator as a function of time.
