WebThe negative sign indicates that the force is attractive (points backward, toward the source). Then the attraction force vector onto a sample mass can be expressed as: = Here is the frictionless, free-fall acceleration sustained by the sampling mass under the attraction of the gravitational source. It is a vector oriented toward the field ... WebMar 18, 2024 · (2) The free-fall acceleration is negative—that is, downward on the y axis, toward Earth’s center—and so it has the value -g in the equations. The free-fall acceleration near Earth’s surface is a = -g = -9.8 m/s2, and the magnitude of the acceleration is g = 9.8 m/s2. How is the acceleration of a free fall constant?
