Renewable resources Natural resources that can be replaced
examples of Renewable water, wind, biomass, solar, and geothermal
Non-Renewable resources A resource or raw material that cannot be grown or replaced once used
examples of non-renewable coal, petroleum, natural gases, oil, and nuclear
Fossil Fuels Coal, oil, natural gas, and other fuels that are ancient remains of plants and animals.
how many forms of energy 7 forms of energy
list 7 forms of energy sound, nuclear, chemical, electrical, light, thermal, mechanical
Sound energy Energy caused by an object's vibrations
Nuclear energy energy from nucleus of the atom
Chemical energy Compound that changes as its atoms are rearranged
Electrical energy Energy of moving electrons
Light energy electrically charged particles.
Thermal energy Heat energy
Mechanical energy motion or position of an object.
How many energy states 2 energy states
List the 2 energy states Kinetic and potential energy
Kinetic energy Energy that an object has due to its motion.
Potential energy The energy that an object has due to the position and arrangement of an object
Force A force is a push or pull upon an object resulting from the object's interaction with another object
Work formula Work= force multiplied by distance
Power formula distance/time
Newton A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second
Newton Meter Forces can be measured
energy conversion A change from one form of energy to another
Friction A force that opposes motion between two surfaces that are in contact
How many factors of friction 4 factors
List 4 factors of friction 1- soft more than hard 2- Big more than small 3- Rough more than smooth 4- High pressure more than low pressure
reduction 1.The definition of a reduction is a decrease or a lessening in amount, or the amount by which something decreases or goes down.
Law of Conservation of energy states... Energy cannot be created or destroyed.
Open System A system in which both energy and matter are exchanged with the surroundings.
Closed system A system in which no matter is allowed to enter or leave
System Boundaries Things are specified to come in or out but sometime it will happen
Wave A disturbance That transfers energy from place to place.
Transverse waves A wave in which the particles move perpendicular to the direction of wave motion
Longitudinal waves a wave in which the particles move parallel to the path of the wave
Crest of a wave is what? the Highest point in a wave
A trough of a wave is what? The lowest point of a wave
Medium of a wave is what? The material the wave is passing through(three forms)
Vacuum Of a wave is what? A space where no particles of matter exist
Electromagnetic waves A form of energy that can move through the vacuum of space.
Mechanical waves waves that require a medium through which to travel
Vibration A repeated back-and-forth or up-and-down motion
Wavelength Distance between wave crests
Amplitude The height of a wave
Pitch A tone's experienced highness or lowness; depends on frequency.
Frequency How many wave peaks pass a certain point per given time
how many speed calculations are there 2 calculations
What is one calculation Speed= Distance/time
One more calculation Speed= Wavelength times Frequency
Physical boundaries boundaries created with naturally occurring features
Mental boundaries mental boundaries give you freedom to have your own thoughts and opinions--and allow others the right to have theirs.
