Changing the Period of a Pendulum
Imagine that your plane has crash landed on a desert island. You don’t have a working clock, so you can’t tell when afternoon teatime is! You set out to make yourself a clock. The plane was carrying a book on whittling wood into gears as well as a book that describes the construction of pendulum clocks—how convenient! However, the pages that describe how to make the correct pendulum are missing. You don’t know how long or heavy it needs to be or how hard it needs to swing to tell time correctly! You’ll have to figure that part out on your own.
How does a pendulum work?
