Acceleration due to Gravity
Subject undefined
Pronunciation: ac•cel•er•A•tion DUE TO GRAV•i•ty
Definition
the rate at which a projectile's vertical velocity changes when air resistance is not a factor; g = -9.8 m/s² or g = -32 ft/s²; the magnitude of these values is also called the "gravitational field strength at sea level"
Example
The vertical velocity of an object in freefall increases or decreases by 9.8 m/sec each second. This change in velocity represents the acceleration due to gravity on the surface of the earth.
