Question

A real spring is not massless, but the mass of your spring was not taken into account in experiment M19. How would the non-zero mass of your spring have affected your experimental values of the spring constant k and the oscillation period T?

Which of the following forces, in addition to the spring force and gravitational force, would have affected, even if only slightly, the measurement of the spring constant k? Select all that apply.

How would the non-zero mass of your spring have affected your experimental values of the spring constant k and the oscillation period T? k was not affected but the measured T were smaller than the values predicted by the equation relating period, measured mass, and spring constant. k was larger than expected but the measured T were not affected. k was not affected but the measured T were larger than the values predicted by the equation relating period, measured mass, and spring constant. k was smaller than expected but the measured T were not affected. Which of the following forces, in addition to the spring force and gravitational force, would have affected, even if only slightly, the measurement of the spring constant k? Select all that apply. the resistive drag force of the air the buoyant force of the air

Explanation / Answer

A real spring is not massless, but the mass of your spring was not taken into account in experiment M19. How would the non-zero mass of your spring have affected your experimental values of the spring constant k and the oscillation periodT?

Ans -
To determine the period of oscillation, T = 2*pi (m/k)^1/2
Where m is the "effective total mass" = mass of the spring added to the mass of the load.

Therefore, Non Zero mass of Spring would increase the Time period of Oscillations and it won't have any affect on Spring Constant k.

Correct Option - (C)

Which of the following forces, in addition to the spring force and gravitational force, would have affected, even if only slightly, the measurement of the spring constant k?

Both the Factors will have affect on Spring Constant measurement -
The resistive drag force of the air & the buiyant force of the air.
