A 2.0 kg body falls in free fall from rest from a point 5.0 m above the ground.
Consider g = 10 m/s². In relation to the body's mechanical energy, we can state that:
I. increases during the entire fall of the body, as the kinetic and potential energies increase;
II. is equal to the sum of the kinetic and gravitational potential energies at any point on the trajectory;
III. at the beginning of the fall is worth 100 J.
Check the correct alternative.
