To determine

The reason for describing the concepts in physics with formula.

Explanation of Solution

Introduction:

The concept obtained from the scientific theory explains the process. It is necessary to explain the quantities in theory to verify the assumptions in the experiment.

The formula is the tool to prove the concept easily. One can only predict the result of the concept. The prediction about the result of the concept may or may not be correct. The error in the result and the method for correction in error is only possible by following the formula of the concept.

Suppose a ball falls from a certain height. One can only explain the process of falling with the concept. Only with the help of a formula, one can find the time of the fall of the ball and the ball's speed at a certain height.

Conclusion:

The concept only explains the process, but the formula verifies the concept. Thus, the concepts of physics describe with formulas.
