Question

Any motion that is regular and repeating is referred to as a periodic motion. Most objects that vibrate do so in a regular and repeated fashion much like this spring seen here. According to Newton's 1st Law of Motion,

A) the greater the mass of the spring, the greater the periodic motion.
B) the lower the mass of the spring, the faster the repeating motion occurs.
C) the periodic motion will continue forces acting on the spring are unbalanced.
D) there is an equal and opposite reaction force that slows down the periodic motion.

Answer 1

C.

Explanation: I took the test and it was correct.

Answer 2

Option C

Step-by-step explanation:

The spring undergoes periodic motion. From Newton's first law, a body keeps moving until an unbalanced external force acts on it. So, the spring would continue to vibrate regularly and in repeated fashion. In the absence of any dampening force, the spring continues to oscillate.

Thus, option C is correct.
