Thus, 10 cm, 50 s, 7 l, and 3 kg are all examples of scalar quantities. Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity. Thus, a velocity of 50 km/h due east, on acceleration of 9.8 m/s 2 vertically downward, and a ...

A physical quantity is the measurable and quantifiable physical property that carries unique information with it. Based on the dependency of direction, physical quantities can be classified into two categories — scalar and vector. Let us now discuss wha
How to Distinguish Between Vector and Scalar Quantities Step 1: Identify the units for the quantity and determine if the quantity described has a direction associated with it. Step 2: Identify the quantity as a vector or a scalar. Vector quantities involve a magnitude (number) with units an...
Physical Meaning- Both scalar and vector quantities describe physical properties or measurements of objects or phenomena in the physical world. Scalars describe quantities like distance, speed, temperature, energy, etc., while vectors describe quantities like displacement, velocity, force, acceleration, et...

Quantities used in engineering and science can be divided into two groups: scalar quantities and vector quantities. Scalar quantities have a size or magnitude and need no other information to specify them. Vector quantities have both a size or magnitude and a direction, called the line of action...
Scalar quantitieshave a size or magnitude only and need no other information to specify them. Thus, 10 cm, 50 sec, 7 litres and 3 kg are all examples of scalar quantities. Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity. ...
