Question | Answer |
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. |
