Exam-style question
Try this first
In a mass-spring system, if the mass is doubled, how does this affect the period of oscillation?.
- A.Period increases
- B.Period decreases
- C.Period remains the same
- D.Period becomes zero
Model answer
What a good answer should say
- Period increases
Explanation
Why this works
The period (T) of a mass-spring system is given by T = 2π√(m/k). If the mass (m) is doubled, the period increases because it is directly proportional to the square root of the mass.
