what is scalar and its 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
Answer:
Scalar Quantity Definition
The physical quantities which have only magnitude are known as scalar quantities. It is fully described by a magnitude or a numerical value. Scalar quantity does not have directions. In other terms, a scalar is a measure of quantity. For example, if I say that the height of a tower is 15 meters, then the height of the tower is a scalar quantity as it needs only the magnitude of height to define itself. Let’s take another example, suppose the time taken to complete a piece of work is 3 hours, then in this case also to describe time just need the magnitude i.e. 3 hours.
Scalar Quantity Examples
Other examples of scalar quantities are mass, speed, distance, time, energy, density, volume, temperature, distance, work and so on.
