underload

-

Under-weight - a seemingly reduced weight of the body under the influence of inertial forces in a non-intrinsic system. It occurs when the force of inertia is opposite to the force of gravity, but it causes acceleration and must be less than the gravitational acceleration (earth). The acceleration of these forces is then less than the weight. The magnitude of the underload is usually determined by the value of acceleration acceleration (g - a difference) expressed as a multiple of gravitational acceleration. It can range from 0 to 1 g, but can not take extreme values ​​of 0 and 1.

Underload can be experienced, for example, in an elevator, which speeds up, downs or brakes, going up.
