Hi, i was just confused on whether certain things will be positive or negative depending on my coordinate system. Lets say im standing on a cliff, and i make down my positive and up my negative. Would any distance below me be positive, and any distance above me be negative? Also the reference point to determine if a height is negative or positive is from where you set the origin right? Thank you.(adsbygoogle = window.adsbygoogle || []).push({});
