What kind of energy would a textbook lose if you dropped it off of a building?
The book’s potential energy can be released by knocking it off the table. As the book falls, its potential energy is converted to kinetic energy. When the book hits the floor this kinetic energy is converted into heat and sound by the impact.
How do you adjust a pendulum clock?
Stop the pendulum to move the pendulum bob up or down to change the pendulum’s effective length. If the clock is running fast, move the bob down or turn the nut to the left. If the clock is running slow, move the bob up or turn the nut to the right. Restart the pendulum and reset the clock hands to the proper time.
What does S and F mean on a clock?
There is usually a small F (Faster) and S (Slower) printed on either side of the dial. French clocks may have an R (Retard) and A (Advance). To make the clock go faster, turn the key toward the F (or A).
How do you fix an overwound clock?
Most likely problem: In actual fact it is almost impossible to overwind a clock. Once the coils of a flat mainspring are in firm contact with one another, than the spring can not be physically wound any tighter. The only way to truly overwind a clock spring is to turn it so tightly that the spring actually breaks.
What are the 2 holes on a wind up clock?
Two Winding Holes This is a ‘time and strike’ clock. The hole on the right is used to power the time train and make the clock keep time. The hole on the left is used to power the strike train, which make the clock strike at the top of the hour. Some of these clocks will also strike once at the half-hour.
How do you wind a 2 hole clock?
The most effective way to wind your clock would be to open the front door, insert the crank, hold the clock steady with your left hand, and turn the crank with your right hand. After winding the clock, set the correct time by moving the minute hand either clockwise or counterclockwise.
What does RA mean on a clock pendulum?
The R A on the pendulum stands for: retard/advance. It is a common pendulum bob, used by many manufacturers, worldwide. As a rule of thumb, the thread on rating nut is designed so that one full turn changes the clock about 2 minutes per week.
How do you fix a clock that won’t wind?
Taking care of your mechanical clock When you do wind your clock, just make sure you have a tight fitting key and that it is inserted all the way. Turn the key slowly and just a half turn at a time. Wind it up until it stops. Do not try to force it to wind any further.
