Question

In experiment is carried out to measure the spring constant of a spring. a mass of 500 g is suspended on the string. its is pulled down a small distance and the time for 20 oscillation is measured to be 34s.

a)explain why the mass performs simple harmonic motion?
b) what is the spring constant?

Answer 1

b/c in simple harmonic motion there is constant oscillation

Answer 2

What Is The Spring Constant ?

Answer 3

7887.68N/m

Answer 4

A)because an experiment is carried out to measure the spring constant of a spring.
B)k=m*number of oscillation /measured time
K=0.5*20/34=0.3N/m
c)x=mg/k=0.5*10/0.3=17m
D)i)change in gravity doesnt affect the time period of SHM.
ii)x=m*g of moon/k=0.5*1.6/0.3=2.72m
