what is Scalar Quantity and Vector Quantity ? Examples
Answers
Answer:
A scalar quantity is usually depicted by a number , numerical value , or a magnitude , but no direction.
A vector is described by both direction and magnitude .
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

A scalar or scalar quantity in physics is a physical quantity that can be described by a single element of a number field such as a real number, often accompanied by units of measurement. A scalar is usually said to be a physical quantity that only has magnitude and no other characteristics.
Example: Speed, Distance, Mass, Time
A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it. Example: Speed is a scalar quantity, but velocity is a vector that specifies both a direction as well as a magnitude.
Example: Velocity, Momentum, Acceleration, Force
