1. MASS : The term Mass represents the matter contained in a body.
2. WEIGHT: The term Weight indicates the amount of force with which the earth pulls a body towards its center.
3. DENSITY : The mass per unit volume of a substance is called its density.
4. TRANSLATORY MOTION : The motion in which all the particles of a body move through the same distance in the same time is called translatory motion.
4 (a). CURVILINEAR MOTION : When a body moves along a curved line, the motion described by the body is called curvilinear motion.
4.(b). RECTILINEAR MOTION : When a body moves along a straight line, the motion described by the body is rectilinear motion.
5. CIRCULAR MOTION/ROTATORY MOTION : A Motion in which a body moves about a fixed axis without changing its position is called the rotatory motion.
6. OSCILLATORY MOTION : The to and fro or back or forth motion described by an object as a whole along the same path, without any change in the shape of the object is called oscillatory motion.
