Question

Give three examples for each of the scalar quantity and vector quantity.

Answer 1

Scalar quantity and Vector quantity

Explanation:

• Scalar quantity-

1. A physical quantity that is completely described by its magnitude can be defined by Scalar.
2. Scalar quantities have a size and also magnitude only and need no other information to prove them.
3. Examples of scalar quantity are such as volume, density, speed, energy, mass, and time.

• Vector quantity-

1. Physical quantities that have both direction and magnitude are defined as vectors.
2. A direction must be along with a number to define a vector quantity as well not all physical quantities can be denoted with magnitude only.
3. For Example, force i.e 2 newtons (N) to the left, displacement 5 kilometres (km) east., velocity i.e 11 metres per second (m/s) upwards
