Is G Positive Or Negative?
Is G Positive Or Negative? Explanation: g is a constant, and is always positive, so any time you see āgā in an equation, use 9.81 m/s2 . So, for example, for gravitational potential energy Ug=mgh , you will always use g=9.81m/s2 . āg is the free-fall acceleration. What does it mean if g is negative?
