Force and Momentum
Physical Science
Term | Definition |
---|---|
Acceleration | increase in the rate or speed of something. |
Displacement | Distance is a scalar quantity. Displacement is an object's change in position, only measuring from its starting position to the final position |
Speed (Distance x Time) | Speed is the distance traveled per unit of time. It is how fast an object is moving |
Mass | Mass is both a property of a physical body and a measure of its resistance to acceleration |
Inertia | a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. |
Average Speed (Total distant x Total time) | The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance |
Momentum | the quantity of motion of a moving body, measured as a product of its mass and velocity. |
Velocity | the speed of something in a given direction. |
Newton's 1st law | The laws are: (1) Every object moves in a straight line unless acted upon by a force. |
Newton's 2nd law | 2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass. |
Newton's 3rd law | (3) For every action, there is an equal and opposite reaction. |
POPULATION | COUNT |
Biosphere | the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms. |
Habitat | the natural home or environment of an animal, plant, or other organism. |
Carrying Capacity | the number of people, other living organisms, or crops that a region can support without environmental degradation. |
Immigration | the action of coming to live permanently in a foreign country. |
Emigration | the act of leaving one's own country to settle permanently in another; moving abroad. |
Symbiosis | interaction between two different organisms living in close physical association, typically to the advantage of both. |
Demographic | relating to the structure of populations. |
Limiting Factors | A limiting factor is anything that constrains a population's size and slows or stops it from growing |
Extinction | the state or process of a species, family, or larger group being or becoming extinct. |
Density | the degree of compactness of a substance. |

Aerodynamics | The branch of mechanics that deals with the motion of gases. |
Friction | The resistant when a body is moved in contact with another. |
Newtons Unit Of Measure | Any division of quantity accepted as a standard of measurement or exchange |
Weight | The vertical force exerted by a mass as a result of gravity. |
Conservation Of Momentum | the principle that the total linear momentum in a closed system is constant and is not affected by processes occurring inside the system |
Force | (physics) the influence that produces a change in a physical quantity |
