1. The acceleration due to gravity at a certain level is 9.78 m/s2. This acceleration varies by 8.28 x 10 -4 m/s2 for every 100 m ascent.   a. Find the height of an object above this level where the acceleration due to gravity is 9.70 m/s2.   b. Find the weight of an object relative to this point whose mass is 80 kg at a height of 10,000 meters.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.
