Term | Definition |
---|---|
Force | In, physics a force in any interaction that, was unopposed , will change the motion of an object |
Static Friction | Static Friction is a force that keeps an object at rest |
Kinetic Friction | Kinetic Friction is defined as a force the acts between moving surfaces |
Drag | pull (someone or something) along forcefully, or roughly |
Field | An area of land marked by the presence of a particular objects or feature in a dune field |
Net Force | Net force is a vector sum of forces acting on a particular body |
Inertia | to remain still or to not move |
Gravity | Gravity (from Latin gravitas 'weight'), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another. |
Free fall | downward movement under the force of gravity only. |
Orbit | In physics, an orbit is the gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or a natural satellite around a planet. |
Electric charge | Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. |
Static electricity | a stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair. |
Electrical conductor | An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. |
Electrical illustrator | An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely |
semiconductor | Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). |
