Question

Define scalar and vector quantities and distinguish between them.

Answer 1

scaler quantities do not have a particular direction while vector quantities have a particular direction

Answer 2

SCALAR QUANTITIES :
Scalar quantities have direction.
These are one- dimensional quantities.
These quantities changes with the change in their  magnitude.
Example: Speed, Temperature, etc.

VECTOR QUANTITIES :
Vector quantities have direction as well as magnitude.
These are multi-dimensional quantities.
These quantities changes with the change in their direction or magnitude or both.
Example: Force, Displacement, etc.
