Triple the Mass in a Mass-Spring System. How does Period Change?

The video tutorial involves a teacher guiding students through solving a physics problem involving a mass-spring system. The problem explores how the period of the system changes when the mass is tripled. The teacher and students work through the mathematical solution, demonstrating that the period increases by the square root of 3. A practical demonstration is conducted to verify the theoretical result, showing a small discrepancy due to experimental error. The session concludes with a farewell to the substitute students.

What is the initial problem discussed in the video regarding the mass-spring system?

• How to determine the amplitude of oscillation

• How to calculate the spring constant

• How to measure the mass accurately

• How the period changes when the mass is tripled

Which formula is used to calculate the period of a mass-spring system?

• T = m/k

• T = k/m

• T = 2π√(m/k)

• T = 2π√(k/m)

What happens to the period of a mass-spring system when the mass is tripled?

• It decreases by half

• It increases by the square root of 3

• It doubles

• It remains the same

In the practical demonstration, what was the observed period when the mass was increased to 150 grams?

• 2.89 seconds

• 2.83 seconds

• 1.67 seconds

• 3.00 seconds

What was the relative error percentage between the observed and predicted period values?

• 0.5%

• 1.5%

• 2.16%

• 3.5%
