Question

a.) How did the change in the weight of the bob affect the resulting period and frequency?

b.) How did the change in amplitude affect the resulting period and frequency?

c.) How did the change in length of the pendulum affect the period and frequency?

d.) What would happen if you used very large amplitudes (Hint: Equation 1 on Page 4 of the procedure might help you see what will happen as the angle is increased)? Check your hypothesis by trial. What amplitude did you use? What is the result?

e.) How close was your calculation of the value of g at your location? What might be a few sources for error in your experimental data and calculations?

f.) What would you expect of a pendulum at a high altitude, for example on a high mountain top? What would your pendulum do under weightless conditions?

Explanation / Answer

part a )

T = 2pi*sqrt(m/k)

if m increase T will also increase but frequncy will decrease by sqrt(m)

f = 1/T

part b )

amplitude does not have any role in time and frequency

part c )

T = 2pi*sqrt(L/g)

if L increase time will increase and Ldecrease time will decrease

reverse in frequency case

part f )

at top g value changes

g' = g*(1-2h/R)

at top g value is decrease so time period will increase and frequency will decrease
