What is potential energy
Potential energy is the build-up of energy in an object waiting to be released. The higher the object the more energy it potentially has.
1
Made by _______
Vibrations
1
Also is known as ______ energy.
heat
1
Travels in _____.
Waves
1
What is electricity?
Electricity is the flow of tiny particles called electrons.
2
what is kinetic energy
Kinetic energy is the release of potential energy resulting in the movement of that object.
2
Travels in _____.
waves
2
Heat energy flows from ______ heat to _____ heat.
high, low
2
What is transparent? Opaque?
Transparent objects you can see through. Opaque objects you cannot see through.
2
Static electricity?
Electrons stay in one place waiting to be discharged.
3
A Rube Goldberg machine shows _______.
The transfer of energy from one object or system to another.
3
Sound waves enter your _______ and are received by your _________.
ear, eardrum
3
Conduction
The heating of an object through direct contact (Grilling)
3
Translucent?
Translucent objects you can partially see through but light passes through it
3
Current electricity?
Electrons flowing from one object or place to another through conductors.
4
Tennis ball on top of the basketball. (Tennis ball and basketball reaction.)
The tennis ball will go super high and fast on the bounce. The basketball will slightly bounce and transfer all of its energy to the tennis ball.
4
What determines the size of a sound wave
Pitch
4
Convection
The heating of an object through a means such as water. (boiling noodles for spaghetti)
4
What is reflection? Absorption?
Reflection is the bouncing off of an object by a light wave. Absorption is the collection of light waves by an object.
4
Conductor vs insulator?
A conductor allows for the easy flow of electrons (copper wires). An insulator protects objects from the electrons in conductors (the rubber casing on your phone charger)
5
Potential and kinetic energy
5
_____ pitch = tight high waves. ______ pitch = long loose waves.
High, low
5
Conductor
Allow for the easy transfer of thermal energy.
5
Refraction?
Refraction is the bending of light through an object
5
Lightning is an example of ______ electricity.
Static
