Energy Stores & Systems
This lesson covers:
1The different types of energy store
2The different ways energy can be transferred
3The concept of 'open' and 'closed' systems
4What the term 'work done' means
Name the different energy stores:
- Th
- G potential
- Ela potential
- M
- Ch
- Elec
- Nu
- K
|
Which of the following is correct?
Energy can be destroyed, but not created
Energy can be created, but not destroyed
Energy cannot be created or destroyed
|
List the different ways that energy can be transferred:
- Mech
- Ele
- Through heating
- Via inf radiation
- Via light or s waves
|
An open system:
|
Is the energy stored in a battery stored in its kinetic, or chemical energy store?
Kinetic
Chemical
|
Can a closed system gain energy from the 'outside world'?
Yes
No
|
When you burn fuel, energy is transferred from the fuel's c energy store to the t energy store of the surroundings.
|
When you throw a ball up in the air, it moves through a gravitational field.
The reason it slows down as it rises is because energy from it's kinetic energy store is being transferred to its:
Elastic potential energy store
Chemical energy store
Gravitational potential energy store
|
Energy is transferred to a light bulb electrically.
How is energy transferred away from a light bulb?
(Select all that apply)
By heating
Mechanically
Via light
|
As an object falls, energy is from its potential energy store, to its energy store.
