WHAT ARE G FORCES? Acceleration is motion in which either an object's speed or direction (that is, its velocity) changes. Mathematically, acceleration and gravity are equivalent, just like energy and mass. A g is a unit for measuring acceleration in terms of gravity.gforces arise whenever something accelerates, as opposed to standing still or moving at a constant speed. 1g is the same as the force that pulls a person toward the ground. When a roller coaster goes around a corner at high speed, the extra pressure riders feel would be measured by a measurement of more than 1g.
WHAT IS CAD: A computer-aided design system combines hardware and software to enable the user to design everything from furniture to cars and airplanes. The user can view a design from any angle and zoom in or out for close-up or long-distance views. CAD systems typically rely on a combination of a keyboard and conventional mouse to control what's on the screen.
