Question

The simple pendulum above consists of a bob hanging from a light string. You wish to experimentally determine the frequency of the swinging pendulum. (a) By checking the line next to each appropriate item on the list below, select the equipment that you would need to do the experiment. ____ Meter Stick ____ Protractor ____ Additional string ____ Stopwatch ____ Photogate ____ Additional masses (b) Describe the experimental procedure that you would use. In your description, state the measurements you would make, how you would use the equipment to make them, and how you would determine the frequency from those measurements. (c) You next wish to discover which parameters of a pendulum affect its frequency. State one parameter that could be varied, describe how you would conduct the experiment, and indicate how you would analyze the data to show whether there is a dependence. (d) After swinging for a long time, the pendulum eventually comes to rest. Assume that the room is perfectly thermally insulated. How will the temperature of the room change while the pendulum comes to rest

Answer 1

Answer:

See explaination

Explanation:

a) We will simply need a STOPWATCH

b) Just let the pendulum to swing 10 times, record the time and then divide it by 10, we have the time period of the pendulum. Then frequency can be found as

f = 1/T

c) As per the time period equation for simple pendulum, we can change the length of pendulum easily to vary the frequency

d) The temperature of room would slightly increase because mechanical energy will convert to thermal energy

e) Period will increase because with increase in temperature, metal will expand and longer pendulum will have more period.
