Answer» VECTOR- A quantity having both magnitude and direction . Scalar- A quantity having only magnitude. Motion- A change of in position of an object over time. Acceleration- Change in velocity of an object with respect to time. Velocity- SPEED with direction. Speed- The rate at which the object covers distance. Distance- Measurement of length between TWO points. Displacement- Shortest distance COVERED by the object. Projectile motion- A form of motion experienced by an object. Centripetal force- The force on an object on a circular path. Gravity- The force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies NEAR its surface. Magnetic field- Area around a magnet. Power- Rate of work done by an object. Wave- Transport of energy without the transport of matter. Simple machine- A mechanical device that changes the direction or magnitude of force. Electricity- Moving of electric charges. |
