Q
Types of energy stores:
A
- Thermal energy stores
- Kinetic energy stores
- Gravitational Potenial energy stores
- Elastic Potential energy stores
- Chemical energy stores
- Magnetic energy stores
- Electrostatic energy stores
- Nuclear energy stores
2
Q
Closed System
A
It is a system where neither matter nor energy can enter or leave. The net (total) change in the total energy of a closed system is always zero.
3
Q
What happens when a system (single object) changes?
A
Energy is transferred, either into or away from the system, between different objects in the system or between different types of energy stores.
4
Q
What does work done mean?
A
Energy Transferred
5
Q
How to falling objects transfer energy?
A
When it falls, it is accelerating with gravity. As it falls, energy from the objects gravitational potential energy store is transferred to its kinetic energy store.
