Question

Define sclar and vector quantities.



pls tell fast...​

Answer 1

Explanation:

hey mate here is ur answer ☺❤❤

Scalars are quantities that are fully described by a magnitude (or numerical value) alone.

Vectors are quantities that are fully described by both a magnitude and a direction.

hope it helps you ☺☺❤❤❤

Answer 2

Weight is a force which is a vector and has a magnitude and direction. Mass is a scalar. Weight and mass are related to one another, but they are not the same quantity. ... Mass and energy are scalar quantities, while momentum is a vector quantity.Mass is a scalar quantity. ... The gravitational acceleration is a vector quantity which has magnitude and direction. As a result, the weight of the object is a vector quantity because of its gravitational acceleration. However, the mass of the object is a scalar quantity.A scalar quantity is a quantity which can be define by its magnitude (or numerical value ) only. For example- distance, speed, time, temperature, etc. ... Therefore, distance is a scalar quantity, its depends only on magnitude not on direction.Examples of scalar quantities include time , volume , speed, mass , temperature , distance, entropy, energy , work , … Example of vector quantities include acceleration , velocity , momentum , force , increase and decrease in temperature , weight , …
