In Episode 20, we are hanging around with a simple pendulum, and discussing just what makes a clock tick (0:36). While introducing the simple pendulum (1:04), we look at an experiment you can easily do from your own home with a string and a mass (1:33). What factors affect the motion of a pendulum (2:46)? You can test each one at home (4:42), but we let you in on all of the secrets eventually. Finally, conservation of energy has a cameo and we talk about find the velocity of a pendulum (7:01).
The Question of the Day asks: (7:47)
How long would a pendulum arm need to be to complete a tick or a tock every 1 second at sea level on Earth?
