http://www.physicsclassroom.com/mmedia/circmot/rcd.cfm What is ‘g force’ in physics? G‚ in physics‚ a symbol relating to gravity. A capital G indicates the gravitational constant‚ as explained in the article GRAVITATION. A lower-case g stands for the acceleration imparted by gravity at the earth’s surface. An acceleration of 1 g is 32. 1 feet per second per second (9.8 m/s2). Fliers and astronauts may experience accelerations many times larger than 1 g. These accelerations are usually expressed
