Free fall - Wikipedia, the free encyclopedia In Newtonian physics, free fall is any motion of a body where its weight is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and it m
Accelerometer - Wikipedia, the free encyclopedia An accelerometer is a device that measures proper acceleration ("g-force"). Proper acceleration is not the same as coordinate acceleration (rate of change of velocity). For example, an accelerometer at rest on the surface of the Earth will measure an acce
Weight | Define Weight at Dictionary.com (physics) the vertical force experienced by a mass as a result of gravitation. It equals the mass of the body multiplied by the acceleration of free fall. Its units are units of force (such as newtons or poundals) but is often given as a mass unit (kilogr

Free Fall and Air Resistance - The Physics Classroom As an object falls through air, it usually encounters some degree of air resistance. Air resistance is the result of collisions of the object's leading surface with air molecules. The actual amount of air resistance encountered by the object is dependent
