Question

The following animated gif is for the next question.

1. Given that the pendulum starts at the black box on the left, at what position(s) has the pendulum completed one period?
(Use capital letters.
If there is more than one answer, separate them with commas but NO white spaces.)
What position(s) signifies(y) one period?

2. Which of the following will increase the period?

A. Degree Greater Angle

B.Less Mass

C.Shorter Length

D.Longer Length

E.Greater Mass

F.Longer Length, Greater Mass, and 3 Degree Greater Angle

G.Longer Length and Greater Mass

H.Shorter Length and Less Mass

3.The following gif is for the next question.

3. What two points define the length of this pendulum?
Write your answer like this M-P

4. If you plot Period2 versus Length, then what is the slope of the line?

A. L

B.R2

C.2pi(L/g)- 1 / 2

D.m

E.T2

G.T

H.4pi2/g

I.4pi2L / g

J.G

5. You time a pendulum for 50 cycles.
Given a stopwatch reading of 2:32.59, what is the period (in seconds)?
s
(Report answer within 1%.)
(Write N/A if there is not enough information.)

The following gif is for the next two questions.

6. What is the value of g according to this plot?
(Use three sig figs. Or write N/A if there is not enough information to answer the question.)
m/s2

7. What is the proper physics translation for the plot above?

Length = 4.13 [m / s2] * Period2 - 0.02 [m]

None of these.

Period2 = 4.13 [m / s2] * Length - 0.02 [s2]

Period2 = 4.13 [s2 / m] * Length - 0.02 [s2]

Period2 = 9.8 [s2/m] * Length - 0.02 [s2]

8. Do you need the mass of the pendulum bob to find the mass of the earth using your value for g?

No

Yes

9. What is G?

G is the proportionality constant used to equate the the force of gravitation with the product of the mass divided by their separation squared.

The acceleration due to gravity (9.8 m/s2.)

Explanation / Answer

1)H,H

2)D.Longer Length

3)A-D

4)H.)4pi2/g

5)183.58=184 sec

6)slope=4pi2/g=4.1253

so g=9.56 m/sec^2

7)Period2 = 4.13 [s2 / m] * Length - 0.02 [s2]

8)NO

9)yes or true
