Question

What is the difference between vector quantity and scalar quantity

Answer 1

VECTOR -

1) the physical quantities which have both magnitude and direction.

2) follows laws of vector algebra

eg - displacement , velocity

SCALER -

1) the physical quantity have only magnitude and no direction

2) follow laws of normal algebra

eg - distance , speed

✦A scalar or scalar quantity in physics is one that can be described by a single element of a number field such as a real number, often accompanied by units of measurement. A scalar is usually said to be a physical quantity that only has magnitude, possibly a sign, and no other characteristics.

✦Vector, in physics is a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude.
