During Upward Motion G Is Negative?

Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s², regardless of the direction. The acceleration is negative when going up because the speed is decreasing. ... If the equation has g in it, like W = mg, direction is implied and the acceleration is positive.

Is upward motion positive or negative?

The velocity-time graph shows a line with a positive (upward) slope (meaning that there is a positive acceleration); the line is located in the negative region of the graph (corresponding to a negative velocity).

What does it mean if g is negative?

A negative ∆G means that the reactants, or initial state, have more free energy than the products, or final state. Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy.
