Question & Answer |
Contributor |
| Q: |
What is the difference between Kinetic Energy and Potential Energy? |
Hiep Hua |
| A: |
Energy is the capacity to do work, move, or can be stored.
- PE = Potential Energy is energy that is from structure, position, or organization
- For example:
- Sugar molecules lock away energy absorbed from sunlight.
- Rocks on high hills have PE due to their position.
- KE = Kinetic Energy is energy of motion.
- For example:
- Molecules can absorb energy and move faster, like warm air/gas when you open an oven.
Follow up:
Q: How does a hot gas compare to a cool gas in terms of energy?
A: Hot gas has absorbed more energy and therefore moves faster, while cooler gases move slower.
