What is the acceleration of a freely falling object?

From an initial velocity of 0 m/sWhat is the acceleration of a freely falling object?
Acceleration on any free falling object is always equal to the force of gravity, which is 9.8m/s^2.





Since acceleration is a vector quantity, it can be denoted as positive or negative. In this case, since the object is moving downwar and not up, acceleration would be negative and so equal to -9.8m/s^2.





Good luck.What is the acceleration of a freely falling object?
Depends where you are. At sea level it is 9.81m/s^2. The Newtonian law is:





a = GM/r^2





where M is the mass of the body you are falling towards, and r is the distance to its centre. So for bodies of the same density d=M/R^3, this means that a=GRd, which is why the acceleration due to gravity is so much greater on Earth than on the Moon.

9.8m/s^2
all depends on the weight of the object being dropped and from how high.
It doesn't matter what the initial velocity is, the acceleration due to gravity is 9.8 m/s^2
