Explanation:
Scalar Quantity
1 . Scalar quantity has only magnitude, but no
direction.
2. Every scalar quantity is one dimensional.
3. Any change in scalar quantity is the
reflection of change in magnitude.

4. Scalar quantity cannot be resolved as it has
exactly same value regardless of direction.
5. Any mathematical operation carried out
among two or more scalar quantities will
provide a scalar only. However, if a scalar is
operated with a vector then the result will b(
a vector.
6. Few examples of scalar quantity: length,
mass, energy, density, etc.
Vector quantity
1 . Vector quantity has both magnitude and
direction.
2. Vector quantity can be I -D, 2-D or 3-D.
3. Any change in vector quantity can reflect
either change in direction or change in
magnitude or changes in both.
4. Vector can be resolved in any direction using
sine or cosine of the adjacent angle.
5. Result of mathematical operations between
two or more vectors may give either scalar or
vector. Dot product of two vectors gives only
scalar; while, cross product or summation or
subtraction results in a vector.
6. Examples of vector quantity: displacement,
velocity, acceleration, force, etc.
