No relationship

Question 23

Period vs Bob mass

Answer 23

Pendulum: no relationship
Spring: positive, linear

Question 24

Pendulum period formula
(derivation)

Answer 24

T = 2π * √(ℓ/g)

Use T² vs ℓ
constant C / g = slope (cancel units)
C is similar to (2π)², C/g = (2π)²/g
T² = ℓ * (2π)²/g, T = √ℓ * 2π/√g

Question 25

Formula for period of oscillating mass on spring (derivation)

Answer 25

T = 2π * √(m/k) Use T vs 1/√k, know mass Slope units = s/√(m/N) = √kg Constant C * √m = slope C similar to 2π T = 2π * √m * (1/√k)

(Expected - Actual) / Actual

Question 29

Period formula

Answer 29

total time / # of cycles

Question 30

Frequency formula

Answer 30

# of cycles / total time

Question 31

Period vs Spring constant

Answer 31

Negative, exponential (downward bulge)

Question 32
