Question

2} If a spring had a spring constant of 5 N/m, what does this mean? 3) If a spring had a period of 2 sec, how many oscillations would it complete in one minute? 4) As the mass on the end of the spring IS. increased, does the period increase or decrease? Isthe period for the 400 g mass double the period for the 200 g mass?

Answer 1

The spring constant is representative of the stiffness of spring. It means 5 newtons force required for unit compression of the spring.More the value of k stiffer is the spring.

period = 2 seconds means that one complete cycle of vibration takes 2 seconds. so in one minute it would complete 30 oscillations.

(4) time period is directly proportional to the mass, which means that if the mass is incrased, the period will also increase.

No the proportionality is with a squre root of mass so the period is not exactly double.

so period for the 400 g mass will be 1.414 times the period of 200 gram mass.

Please rate. Cheers.
