Fitsipiky ny Angovo Kinetika-Asa

Raha miasa amin'ny zavatra iray ny hery manontolo, dia mahatsapa hafainganana ilay zavatra (mihetsika ilay zavatra). Rehefa mahatsapa hafainganana ilay zavatra, dia miova ny hafainganam-pandehan'ilay zavatra. Raha lazaina amin'ny teny hafa, ny asa ataon'ny hery manontolo dia mifandray amin'ny hafainganam-pandeha voalohany sy farany an'ilay zavatra.

Ny asa atao amin'ny zavatra iray noho ny hery tsy miova dia:

W_harato = ΣF s

Ny lalàna faharoan'i Newton dia milaza fa raha misy hery miasa amin'ny zavatra iray, dia mahatsapa hafainganana ilay zavatra.

1.1 Definition of Work

If you push a book on the surface of a table until the book is displaced, you are said to have done work on the book. If an object falls to the ground due to the pull of gravitational force, the gravitational force is said to have done work on the object. On the contrary, if you push an object with all your might to the point that you sweat profusely, but the object does not move at all, you are said to have done no work on the object. In everyday life, people might say that you have done hard work by pushing the object but in Physics, you did not do work on the object because there has been no displacement of the object.
