Thus, the acceleration of the box is 2 meters per second squared. Where F represents the force, m denotes the mass, and a signifies the acceleration. To determine the acceleration, we can use Newton’s second law of motion: Let’s consider a scenario where a person pushes a 10-kilogram box with a force of 20 newtons. James Joule, on the other hand, lived from 1818 to 1889 and made his significant contributions during the 19th century, which was marked by advancements in industrialization and the study of energy. His work was influential during the scientific revolution.
