Question

Why do objects fall to the ground at the same rate

Answer 1

Answer:

According to newtons 2nd law of motion,

"The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object".

                           F=mg

Gravitational acceleration = g =F/m

And we also know g always remains constant which is 9.8 m/s2.

So if the mass of the objects varies, then Force exerted by earth change accordingly to constant the value of g.

Hence gravitation acceleration/ rate of fall will be the same for both heavier and a lighter object.

Answer 2

As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.
