Force&MotionUnit
Key Vocabulary for Sci Method Intro, Energy, and Force and Motion
| Term | Definition |
|---|---|
| motion | an object's position changes when compared to another object |
| reference point | a place or object used for comparison to determine whether something is in motion |
| force | a push or a pull |
| newton | the unit used to measure the strength of a force |
| friction | a force between an object and the surface it is moving over (contact) |
| gravity | a force that pull objects toward each other as a result of their masses |
| net force | the combination of all forces acting on an object |
| speed | how fast an object is moving; the distance the object moves per unit of time; s=d/t |
| slope | the angle of a line on a graph |
| velocity | the speed at which an object travels in a given direction; for example: the storm is moving 25 km/h eastward |
| acceleration | the rate at which velocity changes; (final speed - initial speed) / time |
| inertia | an object's resistance to change |
| Newton's 1st Law of Motion | law that states an object at rest will remain at rest, and an object that is in motion will keep moving (in a straight line) until acted upon by an outside force |
| Newton's 2nd Law of Motion | law that states an object's motion depends on its mass; force = mass x acceleration |
| Newton's 3rd Law of Motion | law that states that for every action there is an equal (in strength) but opposite (in direction) reaction |
| weight | a measure of the force of gravity on an object |
| potential energy | the energy that is stored in an object or system |
| kinetic energy | the energy that an object has because it is moving |
| generator | a machine that can convert kinetic energy into electrical |
| transfer | to move from one object to another or one place to another |
| energy | the ability to make something move or change |
| collision | the moment when two objects hit each other |
| exert | to apply a force |
| mass | the amount of matter that makes up an object |
| matter | anything that has mass and takes up space |
| infer | to reach a conclusion using evidence and reasoning |
| cause | an event or process that leads to a result or change |
| effect | a result or change that happens because of an event or process |
| claim | a proposed answer to a question about the natural world |
| convert | to change from one type to another |
| evidence | information about the natural world that is used to support or go against (refute) a claim |
| model | an object, diagram, or computer program that helps us understand something by making it simpler or easier to see |
| reasoning | the process of making clear how your evidence supports your claim |
| scientific argument | a claim supported by evidence |
| system | a set of interacting parts forming a complex whole |
| hypothesis | A possible explanation about an observation that can be tested by scientific investigations and includes both independent and dependent variables. example: The cotton t-shirt will dry the fastest compared to the wool, polyester, and denim shirts. |
| independent variable | The variable that is changed or manipulated by the scientist Example: the type of mentos added to a Diet Coke Bottle |
| dependent variable | The variable that is measured by the scientist Example: How high the soda spews up into the air |
| control | a standard of comparison example: the plants that receive water are the CONTROL group |
| constants | what you keep the same in an experiment to make it a fair test |
