A vector quantity is described with a direction and a scalar is not.
Scalar quantities are path-dependent quantities and vector quantities are not.
Explanation:
Scalar quantity:
- It is a physical quantity that only has magnitude.
- It is a 1-dimensional
- Its changes when magnitude changes.
- It can't be resolved.
- It is a path-dependent quantity.
- If any mathematical operation is applied between two or more scalar quantities will give a scalar.
- For example: mass, time, energy, etc
Vector quantity
- It is a physical quantity that has magnitude and direction.
- It can be the 1-dimensional,2-dimensional, or 3-dimensional
- Any change in it changes its direction or magnitude or both.
- It can be resolved.
- It only depends on the initial and final values of quantities.
- If any mathematical operation is applied between two or more vector quantities will give a scalar or vector.
- For example: force, velocity, pressure, etc.
So from this, we can conclude that the true statements out given statements in the question are:
A vector quantity is described with a direction and a scalar is not.
Scalar quantities are path-dependent quantities and vector quantities are not.
