An object on the end of a spring is oscillating in simple harmonic motion. If the amplitude of oscillation is doubled, how does this affect the object’s maximum speed?

The maximum speed of the oscillating object doubles as well.

Explanation:

The oscillatory motion of the object on the spring can be modelled using this equation below:

Where

Vmax = the maximum speed of the oscillating object.

A = Amplitude of the oscillating object.

= angular velocity of the oscillating object.

If the amplitude, A becomes doubled, the new amplitude will be = 2A.

As a result,  

This shows that the maximum speed has doubled in its value

charge because it doesnt matter if it is a negative or positive
