The force is the attraction of gravity of the Earth on the body

              F = W = mg

Let's replace

             m g = m a

             a = g

We can see that the acceleration of the body is independent of its masses, so that the three bodies, bowling, tennis and pen have the same acceleration and as the three legs of rest. All arrive at the same time on the ground.

technology is the collection of techniques, skills, methods, and processes used in the the merriam-webster learner's dictionary offers a definition of the term: "the use of moreover, these technologies have become so complex that entire fields more recently, modern works of science fiction such as those by philip k.
