Assignment:
Question 1. What is α given a = 0.365 [ms-2] and diameter of disk with uniform mass distribution = 19.1 [cm].
Question 2. Using information found in previous question, if the dropping mass is 145[g], then what is Τ?
Question 3. I have a plot whose vertical intercept is 0.00434 [Nm] If the bearings are 2 [mm] from the center of the wheel, then what is the force of friction?
Question 4. You time a pendulum for 50 cycles. Given a stopwatch reading of 2:47.92, what is the period (in seconds)?
Question 5. According to the relationship between torque and angular acceleration, what happens when you have more torque (given a constant rotational inertia)?
- The angular acceleration decreases.
- Not enough information to know.
- The angular acceleration stays constant.
- The angular acceleration increases
Question 6. Data's vertical intercept should exist directly because of:
- friction between string and big wheel
- my lab partner messing up the data
- mass of string
- frictional force
- extra mass of pulley
- the torque due to friction; τfriction
Question 7. Which of the following will increase the period?
- Shorter Length and Less Mass
- Longer Length
- Shorter Length
- Longer Length and Greater Mass
- Longer Length, Greater Mass, and 3 Degree Greater Angle
- 3 Degree Greater Angle
- Greater Mass
- Less Mass
Question 8. Given that the pendulum starts at the black box on the left, at what position(s) has the pendulum completed one period?
