Question

Carlos is analyzing the results of a recent scientific study about gravity. Scientists recorded that the experimental value of gravity was 10.24 m/s² and the general accepted value of gravity is 9.81 m/s².

Calculate the percent error of the experimental versus accepted values of gravity.

5.01%
4.38%
2.66%
9.27%

Answer 1

Percent error = |experimental − accepted| / accepted × 100%
= |10.24 − 9.81| / 9.81 × 100% = 0.43 / 9.81 × 100% ≈ 4.38%

Answer: 4.38%
