Chapter 1.1, Problem 7SSC

To determine

To Explain:Whether the accepted value of acceleration due to gravity be tossed out to accommodate new value.

Explanation of Solution

Introduction:

The accepted value of acceleration due to gravity is $9.8\text{m}\cdot {\text{s}}^{-2}$ . It has been accepted after repetitive calculations in many experiments and thus, is now recognized universally.

If in an experiment, a different value of acceleration due to gravity is obtained, there must be some friction or error in calculation or problem with the measuring instrument. So, there could be many factors affecting the calculation and for that the accepted value cannot be tossed out.
