Energy adds up Flashcards
Define energy store
The different forms energy comes in.
define conservation
Doesn’t get destroyed or used up it is just transferred ‘ changed’ into another form
Dissipate
Energy has been spread out or ‘wasted’ by heating the environment
What is energy measured in
Joules
What is the acronym for energy stores

Names
Name all the energy stores
1- Magnetic
2- Kinetic
3- Heat/ therma;
4- Light (radiation)
5- Gravitational
6- Chemical
7- Sound ( radiation, waves)
8- Elastic
9- Electrical
10- Nuclear
What is magnetic energy and example
It is energy found in magnetic field (magnets) e.g: iron and a magnet
What is kinetic energy and examples
Energy found in moving objects . E.g: Moving car
What is thermal energy and examples
Energy stored as heat E.g: fire
What is light energy and example
Anything that gives of light: torch
What is Elastic energy and examples
Energy found in stretched object e.g: rubber band
What is chemical energy and examples
Energy found in batteries, foods and fuels
What is nuclear energy and examples
Energy found in splitting or fusing of atoms e.g: sun
What is gravitational potential energy and examples
Energy found in raising objects from the ground. E.g: Apple in a tree
What is Electrical energy and examples
Energy found in flow of electrical current in a wire
What is Sound energy and examples
Anything that gives of sound. Examples: TV
State the law of conservation of energy
The law of conservation of energy states that energy doesn’t get destroyed or used up, it is just transferred ( changed) into another form.
State the energy transfer of stores in the following example
1- Coal
2- Fire
3- Train
1- Chemical
2- Thermal
3- Kinetic
State the energy transfer of stores in the following example
1- Battery
2- Wire
3- Lamp
1- Chemical
2- Electrical
3- Light
State the energy transfer of stores in the following example
1- Sun
2- Plant
3- Human
1- Nuclear
2- Chemical
3- Kinetic
State what happens after in the following scenario
1- Unburnt fuel
2- More oxygen
3- Cold soup
4- More chemical energy
5- Less thermal energy
1- Less fuel
2- More carbon dioxide and water
3- Hot soup
4- Less chemical energy
5- More thermal energy
Explain why energy saving light bulbs are better
Energy saving light bulbs are better because they need less fuel to produce the same amount of light so it saves you money.It also doesn’t waste as much energy as normal light bulbs so they are better for the enviroment
- Can energy be used up or destroyed? What is the scientific word related to this?
Energy can not be used up. It is transferred. This is called conservation of energy
- What type of energy do devises produce as waste. Why is this bad?
Heat energy is usually the waste store of energy and it’s bad because it wastes money.
- Where do we find chemical energy?
Foods.fuels and batteries
the bowling ball was raised up to the height of the persons face, the ball was released with no added push from the person, then it returned. Explain in detail what happened using terms from energy store
The ball was raised up to the height of the person’s face, which gave it gravitational energy.
When the ball was released, it fell so it gained kinetic energy.
Then it returned, it did not gain any energy so ut returned to the same height of the person’s face.
What are the main energy transfers in a car engine
Chemical –> 1- Thermal
2-Kinetic
3- Sound
What energy stores are generally wasted
Heat is usually wasted
What does an energy transfer diagram show?
It shows us the input and output of transfer of energy stores
Are you going to work hard today
yes :)
