SUMMARY

The discussion addresses the proper handling of significant digits when solving multi-equation problems in physics, specifically when calculating acceleration and net force. The consensus is to avoid rounding intermediate results until the final answer is obtained to maintain accuracy. The equations referenced include acceleration (a = (vf - vi) / t) and net force (fnet = ma). Participants recommend using calculators that allow storing values to enhance precision throughout the calculations.

[SOLVED] Significant Digits

I know how to do significant digits, but was wondering about answers involving multiple equations. If I find acceleration first, then find net force, should I wait to round the answer until the end?

a=vf-vi/t and then fnet=ma

To reiterate, should I keep acceleration long, or round it to complete the group of equations above?

Thank you very much!

Don't round off till the end!

Are you able to store values to letters on your calculator? I would suggest doing that if you can.
 
Yeah. Thanks a lot, I'll make sure to do that.
