Energy Booklet Flashcards
If an object has energy then it is capable of…
…Doing work
What is Kinetic energy
The energy of moving
What is Gravitational Energy
The energy stored by anything lifted up
What is Elastic energy
The energy stored by a stretched or compressed material before it’s released
What is energy measured in
Joules (J) or kiloJoules (kJ)
What is the rule about energy
It cannot be created nor destroyed only Change forms
What diagram thing can you make to show energy distribution
Sankey diagram
Name three types of energy
Chemical,gravitational,nuclear,thermal,light,electric ,light , sound plus more
What is chemical energy
Energy stored in fuels,batteries and food
What is kinetic energy
The energy of something moving
What energy transfers happen with a lawn mower.
Chemical goes to kinetic,sound and thermal
How many joules in a kilo joule
1000
If there is 10 joules of electric energy and three joules of useful energy how much is wasted
7 joules
What is the rule of conservation
Energy can neither be created or destroyed
(kJ)
kiloJoules
(J)
Joules
How many joules in 0.4 kilojoules
400
What energy transfers happens when you turn on the lights
Electric goes to thermal and light sometimes sound if you have terrible lights
What is nuclear energy
The energy stored in the nuclei of atoms.This is released in nuclear reactions in the sun and hydrogens bombs
cm*y=m
y=100
kiloJoule*y=Joule
y=1000
Stretch energy
The energy stored by a stretched or compressed material before being released .
Gravitational potential energy
The energy stored by anything lifted up
Thermal energy
Also called heat energy,this is the energy an object has beCAUSE IT IS HOT
Apply this rule to one object:
Object: type of energy taken in →types(s) of energy given out
e.g. An electric kettle: electric → sound + heat
