Question

Can the acceleration due to gravity(g) can be 10.2 in experiment(simple pendulum)?

I got g = 10.2 m/s using the simple pendulum experiment. Is the answer be correct !

Answer 1

No the correct answer is `9.81"m/s"^2`. There must be an error in your measurements or calculations.

Answer 2

A bit close, the actual value is 9.8 `m`/`s^2`

Explanation:

There might be some systematic errors as well, while you were doing the experiment or errors caused by the equipment you used.
It is systematic errors that affect result.
