Here in this post, you will find the difference between Scalar and Vector Quantity in tabular form with suitable examples. 

Scalar Quantity

Vector Quantity

Definition: SCALAR QUANTITY is those physical quantities which have only magnitude, no direction.

Definition: VECTOR QUANTITY is those physical quantities which have both magnitude as well as direction.

SCALAR QUANTITY is always 1-dimensional.

VECTOR QUANTITY can be 1-D, 2-D, or 3-D.

SCALAR QUANTITY changes with change in its magnitude.

VECTOR QUANTITY changes with change in its magnitude or direction or both.

SCALAR QUANTITY obey algebraic rule for operation such as addition and multiplication.

VECTOR QUANTITY obey vector algebra rule for operation such as addition and multiplication.

SCALAR QUANTITY can divide another scalar quantity.

VECTOR QUANTITY cannot divide another vector quantity.

SCALAR QUANTITY can be represented by an ordinary letter.

VECTOR QUANTITY can be represented by a letter with a cap or arrow on it.

SCALAR QUANTITY is described by a number and a suitable unit.

VECTOR QUANTITY is described by a number, a suitable unit, and its direction.

SCALAR QUANTITY when multiplied with a scalar quantity always remains a scalar quantity.

VECTOR QUANTITY when multiplied with a vector quantity can be a vector quantity or a scalar quantity.

Distance, Speed, Mass, etc. are SCALAR QUANTITIES

Displacement, Velocity, Acceleration, etc. are VECTOR QUANTITIES.
