1) What is the purpose of the experiment? 2) A solid disk of mass m is rolling a long a surface. Its center has the velocity v. What is the kinetic energy of the disk? 3) The falling block causes the disk to rotate. What is the speed of the block after it has been fallen a distance h from rest. 4) What can you say about “ ”? That is, κ a) What is it called? (Don’t write “kappa”) b) What are its dependencies? c) What differences are between and k (spring constant)? κ d) How can you determine experimentally? κ 5) Comment on the physics laboratory (content, time, grading, assistants, yourself, etc.) 6) In this experiment you will be using two new equipments that you haven’t used before. Give their names. 7) Make an analogous between simple harmonic oscillation and angular simple harmonic oscillation. 8) Show that the potential energy of an angular simple harmonic oscillator can be written as follow: U( ) = (1/2) θ κθ 2 8) What is the purpose of this experiment?

9) Suppose that during a holiday trip to Antalya, you have bought a classic watch working with simple pendulum. You brought it to Ankara. Then after a while your physicist friend tells you this watch will not work properly. a) Is that true? Will watch shows correct time? Is it late or early? Explain why? b) Write the total energy of rotating disk with a torsional oscillator in terms of l, and . κ Hint: As you may know gravitational acceleration in Ankara is less than in Antalya. 10) Write the units of I , θ , T , and . κ a) Does torsional constant depend on the torque applied? Give your κ reasoning. b) Does oscillation period T depend on the torque applied? Give your reasoning. 11)Using your results from the previous experiments try to write down a relation for the torque applied on a torsional oscillator (in terms of displacements and the relevant torsional oscillator constants). Be careful with the signs. 12) Write down the energy of a torsional oscillator. 13) Write down the rotational analogous of the Hooke’s Law. Check the units. 14) Write down the frequency (or period) of the small oscillations regarding the spring constant in rotational motion. Again check the units. 15)
