What do you mean by motion ?What physical quantities are required for describingmotion ? |
|
Answer» In physics, motion is the PHENOMENON in which an OBJECT changes its POSITION over time. In describing motion we deal with three basic quantities: Length, Mass and Time: L,M,T. By a point we understand it as a place – but it has no size ! A length is MADE up of an infinite NUMBER of points each of which has no ' size', but length we can measure. |
