Exam-style question
Try this first
In a mass-spring system undergoing simple harmonic motion, if the mass is doubled, how does the period change?.
- A.The period doubles.
- B.The period remains the same.
- C.The period increases by a factor of √2.
- D.The period decreases.
Model answer
What a good answer should say
- The period doubles.
Explanation
Why this works
According to the formula T = 2π√(m/k), if the mass m is doubled, the period T increases, specifically it doubles since T is proportional to the square root of the mass.
