Oscillations and Simple Harmonic Motion Quiz

What is the purpose of measuring 10 time periods in the oscillation experiment with springs?

• To reduce percentage uncertainty

• To make the experiment more complex

• To increase the time period

• To ensure the spring is working

How does varying the initial amplitude affect the time period in simple harmonic motion?

• It increases the time period

• It decreases the time period

• It has no effect on the time period

What is the relationship between t squared and mass m in the time period equation for springs?

• t squared is independent of m

• t squared is equal to m squared

• t squared is inversely proportional to m

• t squared is directly proportional to m
