How does the frequency change with increasing mass? 2. How does the frequency change if the spring constant increases? 3. Explain the physical meaning of the spring constant in terms of "stiffness" or "softness" of a spring.Explanation / Answer
1. Frequency is inversely proportional to the time period and time period is directly proportional to the sqrt(m). Hence frequncy os inversely proportional to 1/sqrt(m). As mass incrases the frequency decreases.
2. Frequency is directly proportional to the sqrt(k). Hence frequency increases.
3. Larger value of k required large value of force to deform it from its natural length.Every material have different value of spring constant.
