Question

Define scalar quantity​

Answer 1

Scalar quantities are physical quantities which have a magnitude and direction.

e.g. in 5 km, 5 is the magnitude(number) and km is the unit.

some scalar quantities are mass, length, distance, speed, power, energy, temperature etc.

Answer 2

Answer: Values with magnitude but without direction

Step-by-step explanation:

Majorly there exists two types of quantities, Scalar and Vector.

Vectors: Quantities, with magnitude and direction.

Example: Force, Displacement

Scalars: Quantities, with magnitude but without direction.

Example: Weight, Length, Quantity

we do not need direction to define weight,

it is just 5 kilograms, and NOT 5 kilograms towards east.
