Question

This experiment is about free fall. The ball is released at a certain height and it assumes that gravity is uniform on the surface of the earth. Explain why this assumption is established and how to measure more accurate gravitational acceleration.

Answer 1

Dear student,

As per the laws of Newton, free fall was defined as the motion of an object under the sole influence of gravity. Gravity is the only force acting upon it. As per newtons law, he has proved that a body in free fall follows an orbit such that the sum of inertial forces becomes zero. Even the planets are in free fall. Free falling objects does not encounter air resistance. Certain examples include a stone dropped down to an empty well. Even though many experiments are done to measure more accurate gravitational acceleration, still it is not been deployed and the concept of free fall theory is been used.

Hope u got it

Thank u
