Physical Properties
Explanation:
You are able to see physical properties but are unable to see chemical properties.
Give 3 Examples of where potential energy was converted to knlinetic energy:
Curtain
A ball before moving
An apple from the tree then falling down
When the Curtains are still, we call the that potential energy. If you move the curtains around, that is kinetic energy
The ball is still, that is potential energy. Then the ball is moving, the is kinetic energy
There is a apple ganging from a tree, that is potential energy. That apple is fall, this is kinetic energy
Hope this helps
Don't type or write in the answer, I'm not sure what from the lab means. These are a few potential into kinetic energy I could have think of!
