1. Suppose that a grandfather clock (a simple pendulum) is running slowly; that is, the time it takes to complete each cycle is greater than it should be. You should shorten the pendulum to make the clock keep correct time. True or False? 2. In principle, the motions of a simple pendulum and an object (oscillating) on an ideal spring can both be used to provide the basic time interval or period used in a clock. Which of the two...

A grandfather clock has a pendulum that consists of a thin brass disk of radius 21 cm and mass 1 kg that is attached to a long, thin rod of negligible mass. The pendulum swings freely about an axis perpendicular to the rod and through the end of the rod opposite the disk. The pendulum should be designed so that its period is 2 s for small oscillations when the gravitational acceleration is 9.8 m/s2. (a) What should the length...

Simple Pendulums “Periodic motion” is motion that repeats itself. One example of “periodic motion” is a simple pendulum. The mass of a simple pendulum is all at its bottom. For a simple pendulum, the time it takes for one complete swing (a.k.a. the “period”of the pendulum) depends only on the length of the string: Period = 2π times square root of (length / g). If the length is measured in centimeters and the pendulum is on Earth where g =...

1. You determine the period of the pendulum motion. Keeping the length of the string constant, you replace the object with one that has bigger mass. Will the period be affected? a. No, the period will remain the same because it depends only on the length of the string. b. Yes, the period will increase because heavier objects have greater inertia or have greater resistance to changes in their state of motion. c. Yes, the period will decrease because the...

We have two oscillators, used to measure time. One is a vertical mass-and-spring system. The other is a simple pendulum. On earth the two systems have the same period. How do their periods compare on the moon? A. Both periods become longer. B. only the pendulum's period becomes longer C. Only the mass-and-spring's period becomes longer D. Neither period changes at all. E. none of the above If a mass hangs from a vertical spring and is moving up and...
