The ability to do work (howthings change and move) is called:
|
Energy
|
|
|
Energy that is in motion is called ________________ energy.
|
Kinetic
|
|
|
Moving water, wind, and other energy in motion are examples of what kind of energy?
|
Kinetic Energy
|
|
|
Stored energy, that if released would do work, is called __________________ energy.
|
Potential
|
|
|
Water in a lake at the top of a mountain, or a roller coaster cart sitting at the top of a hill are examples of ___________________ _______________.
|
Potential Energy (if released, the water and the cart would do work)
|
|
|
Energy (can OR cannot) change forms?
|
Energy CAN change forms. (For example, potential energy can change to kinetic energy).
|
|
|
A type of energy that canbuild up in one place, or flow from one place to another, is called:____________________________
|
Electricity
|
|
|
When electricity flows from one place to another, it is called ______________ electricity.
|
Current
|
|
|
When electrons move, they carry electrical energy from one place to another place. This happens with appliances and lightning bolts, etc. This flow of energy is called: ________________
|
Electricity
|
|
|
When electricity gathers in one place, it is called ________________________ electricity.
|
Static
|
|
|
This type of electricity is caused by electrons (tiny particles that orbit around the edges of atoms) that each have a slightly negative charge. When electrons are knocked free and gather on an object, this leads to _________________ electricity.
|
Static
|
|
|
When you rub a balloon across your hair, electrons are knocked free and gather on your hair. This leaves the balloon with less electrons and your hair with extra electrons; leaving your hair slightly negatively charged. This leads to ________________ electricity in your hair.
|
Static
|
|
|
When electricity flows fromone place to another, it's called _______________ electricity.
|
Current Electricity
|
|
|
When electricity gathers in one place, it's called _____________________ electricity.
|
Static
|
|
|
When electricity flows from one place to another, it's called ___________________ electricity.
|
Current
|
|
|
A form of electricity we can detect with our sight is ___________________.
|
Light. Light is a form of energy which our sense of sight can detect.
|
|
|
This form of energy is made of electromagnetic radiation and travels in a straight path.
|
Light
|
|
|
What travels faster than the speed of light?
|
Nothing.
|
|
|
There are different _____________________ of light because light waves have different wavelengths.
|
Colors
|
|
|
_______________ light hasthe longest wavelength.
|
Red
|
|
|
______________ light has the shortest wavelength.
|
Violet
|
|
|
The primary colors are:
|
red, yellow, and blue (mixing these three colors makes all other colors, including white).
|
|
|
The bouncing back of light waves when they hit an object with a smooth, shiny surface is called:
|
Reflection
|
|
|
The bending of light as it passes from one transparent substance to another (like from air to water, for example) is called:
|
Refraction
|
