2.1 and 2.2 Forms Of Energy/Conservation of Energy Flashcards
What is energy?
The ability for something to do work, the motive for every process and function
What can energy never do?
Be created or destroyed
What is an energy transfer?
The same type of energy moving
What is an energy transform?
One type of energy changing into another
Name the 9 types of energy
- kinetic
- heat/thermal
- light
- gravitational potential
- chemical
- sound
- elastic potential
- electrical
- nuclear
Name a way to remember the energy types
- kids
- hate
- learning
- g
- c
- s
- e
- energy
- names
What type of energy does any object above the ground have?
Gravitational potential
Name the energy transfer that happens when an object falls
Gravitational potential –> kinetic
Name three forms of stored energy
- gravitational potential
- elastic potential
- chemical
What form of energy does a compressed spring have?
Elastic potential energy
Where does the energy stored in your muscles come from?
From the food that you eat
Name the main energy transfer and waste energy of a torch
Main energy transfer:
Chemical –> light
Waste:
Heat
Name the main energy transfer and waste energy of a car
Main energy transfer:
Chemical –> kinetic
Waste:
Heat
Sound
Name the main energy transfer and waste energy of an alarm clock
Main energy transfer:
Electrical (or chemical if it’s battery operated) –> sound (kinetic if old fashioned)
Waste:
Heat
Why is the total amount of energy the same before and after an energy transfer?
Because energy can’t be created or destroyed
