Free Falling Object. the value of g is 9.8 meters per square second on the surface of the earth. The gravitational acceleration g decreases with the square of the distance from the center of the earth.

What is g in free fall?

A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). ... A matter of fact, this quantity known as the acceleration of gravity is such an important quantity that physicists have a special symbol to denote it - the symbol g.

Is g negative or positive in free fall?

Problem-Solving Strategy: Free Fall

Decide on the sign of the acceleration of gravity. In (Figure) through (Figure), acceleration g is negative, which says the positive direction is upward and the negative direction is downward.
