what is difference betweestance distance and displace ment ?Are these equal in magnitude? Give their s. i. units
Answers
Answer:
the distance travelled by a body is the actual length of the path covered irrespective of the direction in which the body moves.
the shortest distance measured from initial to the final position of an object is known as displacement.
distance is a scalar quantity where as displacement is a vector quantity.
distance travelled has only magnitude where as displacement has both magnitude and direction.
the si unit of distance and displacement is meter (m).
Answer:
Distance-The actual length of the path travelled by a moving body in a given interval of time is called distance.It is scalar quantity which is expressed in size and magnitude . It is always greater than or equal to displacement.It is always positive. Distance covered by a moving body or object in different directions can be added by simple arithmetic. It's SI unit is metre
Displacement -It is the shortest day distance of a moving body between the initial and final positions in a specified direction is known as displacement. It is a vector quantity which is expressed only in magnitude and direction. It is always lesser than or equal to distance. It may be negative, positive or zero. Displacement of a moving body at various instants during its course of motion cannot be added by simple arithmetic. It's SI is metre
