| 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. |
