Explanation:
Detailed explanation-1: -Acceleration of free fall is the acceleration produced when a body falls under the influence gravitational force of the earth alone. It is denoted by g and its value on the surface of the earth is 9.8 ms−2.
Detailed explanation-2: -The symbol of acceleration due to gravity is “g”.
Detailed explanation-3: -A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). This numerical value for the acceleration of a free-falling object is such an important value that it is given a special name.
Detailed explanation-4: -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.
