Question

What is scalar quantity??​

Answer 1

Answer:

Scalar quantities have 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. (b) Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity.

Answer 2

In physics, scalars are physical quantities that are unaffected by changes to a vector space basis. Scalars are often accompanied by units of measurement, as in "10 cm".
