If a filled water bottle is attached to a string hanging from a pivot point in the ceiling and is pulled back 9 ft and is held just under the chin of a 5'8'' tall person, will it swing and hit another 5'8'' person standing 18 ft away?
The students tackle Lab #4 in which they investigate Potential Energy (Gravitational Potential Energy) and how it Transforms into Kinetic and back again.
The students will swing an empty water bottle, 100g of water in the bottle, and 100g of sand in the bottle. Each time, they will record the number of swings before the pendulum comes to rest. The students should observe and/or explain...
1. How many swings the pendulum takes.
2. The general speed at which it swings
3. The distance it swings out with each consecutive swing.
4. Why does the pendulum stop swinging sooner/later depending on mass of pendulum.
5. What is responsible for the pendulum's lack of energy?
A couple picks from lab 3...passing energy along.
