What is probably the greatest source of error in the experimental procedure? |

Explanation

There are two types of experimental error: one is random error and the other one is symmetric error.

The random error(s) is that kind of error which occurs randomly during the experiment. It is not possible to predict the source, sign and magnitude of this error(s).

The symmetric error(s) is that kind of error(s) which occurs due to faulty instruments such as biased tools or calibrated instruments. It is possible to calculate the source, magnitude and the sign of the error.

This experiment deals with a linear track, a car on it. And the symmetric errors can be arised due to the wrong setup of the linear track and the other errors will be random errors.

Verified Answer

linear track.
