Hi, im doin a lab report finding the accelration of gravity. The setup uses an air track, and a rider, photogates etc. One question asks: If there is friction in the system, will it increase or decrease your experimental value of g.(adsbygoogle = window.adsbygoogle || []).push({});

I know that the answer is that it will decrease my experimental value of g because friction opposes gravity.

How can I show some work/Prove This?
