## MEASUREMENT IN PHYSICS

MEASUREMENT IN PHYSICS Measurement of area and volume Concept & measurement of time and ways of measuring time. MEASUREMENT OF VOLUME Volume of liquid objects is measured using instruments such as cylinder, burette, pipette, eureka can, etc. For regular solid objects, their volume could be determined using their mathematical formula. S/N Solid Object Formula for

## Position, Distance and Displacement

Concept of position, Concept of distance and displacement Distinction between distance and displacement. CONCEPT OF POSITION The position of an object is its location in space. It is usually expressed in relation to a reference point. To locate an object in space, a co-ordinate system is needed. It is usually a mathematical construct with co-ordinates.
