what is free fall and Acceleration due to gravity
Answers
Answer:
A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). ... The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s. There are slight variations in this numerical value (to the second decimal place) that are dependent primarily upon on altitude.
Answer:
Explanation:
free fall in simple words means when an object fall from a certain height , only gravitaional force acts on it as it comes down . this kind of motion where an body in motion because of garvitaional force only it is called free fall.
Acc. to 2nd law of motion
F=ma so if gravitaional force is acting on a body of mass 'm' there must be an acceleration. this acceleration is known as acceleration due to gravity and is denoted by letter g .
