What does energy do?
Energy makes things happen
What is the effect of energy called?
Work
What are the forms of energy?
Kinetic, Heat, Light, Sound, Electrical
What is kinetic energy?
Energy of movement
What is heat energy?
Energy that comes from the sun, flames of electrical changes.
What is light energy?
Energy that comes from sun,light or fires.
What is sound energy?
Energy that comes from vibrations from sound.
What is electrical energy?
Energy that comes from power, solar panels, batteries
What is potential energy?
Stored energy
What does potential energy do?
Gives objects the potential to make things happen.
What are the four types of potential energy?
Gravitational, Chemical, Elastic, Nuclear
What is Gravitational energy?
Energy stored in an object when it is above the ground
What is Chemical energy?
Energy stored in substances
What is Elastic energy?
Energy stored in something stretched/squahsed
What is Nuclear energy?
Energy stored in particles that make up all matter
What is Energy Transfer?
When energy can be passed from one object to another
What are the 3 ways Heat can be transferred?
Conduction, Convection,Radiation
When does Conduction happen?
Conduction happens when heat is transferred between 2 objects that come into contact
When does Convection happen?
Convection happens when heat is transferred between liquids and gasses
When does Radiation happen?
Radiation happens heat radiates from a hot object
What is Energy Transformation?
When energy can be transferred from 1 type into another
What are the 3 steps of a flow chart?
Input, Useful, Wasted energy
What is Energy Efficentcy?
The measure of how much input energy is converted into wasted energy
