P1: Energy Stores & Conservation of Energy Flashcards
1
Q
What is a storage?
A
The energy stays in the same object.
2
Q
What is a transfer mechanism (pathway)?
A
Energy moves from one energy store to another.
3
Q
How can energy be transferred?
A
By heating, waves, an electric current, or when a force moves an object.
4
Q
What are the 5 energy stores?
A
- Chemical energy: fuels, food, batteries
- Kinetic energy: object moving
- Gravitational potential energy: object above ground
- Elastic potential energy: springy object
- Thermal energy: temperature
5
Q
What are the 4 energy pathways?
A
- Electrical current: joules
- Radiation: light, sound
- Mechanical work: when a force acts over a distance
- Heating: due to a difference in temperature
