## gravitational acceleration

[‚grav·ə′tā·shən·əl ak‚sel·ə′rā·shən]
(physics)
The acceleration imparted to a body by the attraction of the earth; approximately equal to 980.7 cm/s2, or 32.2 ft/s2.

The determined value of acceleration is referred to a certain level over the benchmark, which explains the necessity to determine the true value of the gravitational acceleration gradient for the reduction of the measured value to the benchmark level using the real gravitational acceleration gradient and assuming its constancy during the three survey epochs.
This should emphasize the distinction between two contiguous but fundamentally different physical situations: when an object is held in hand, and thus subject to forces, and when an object is in free fall, and thus subject only to gravitational acceleration. In addition, it is likely that students would benefit of functional learning, i.e., a procedure which help students to learn correct integration rules through the use of cognitive feedback.
Other terms appearing in (2) are the gravitational acceleration g = 9.81 m/[s.sup.2] and a viscous damping coefficient [c.sub.v].
The model found that Mount Nevado Huascaran in Peru has lowest gravitational acceleration, at 9.7639 m/s2, while Arctic Ocean has the highest at the surface at 9.8337 m/s2.
Where G--the gravitational acceleration, [OMEGA]--the vector of gravitational torsion field, E--the electric field strength, B--the magnetic induction, [[epsilon].sub.0]--the vacuum permittivity.
This could be due to the absence of a gravitational acceleration dependent, intraventricular hydrostatic pressure difference (Delta P) in microgravity that exists in the ventricle in normal gravity due to its size and anatomic orientation (7).
overload torque up to 12 Nm *; ambient temperatures up to 200[degrees]C (390[degrees]F); atmospheric pressures up to 1700 bar (25000 psi); submerged oil operation (flooded in hydraulic fluid); vibrations up to 25 grms; impulses and impacts up to 100 G (100 times gravitational acceleration); and service life approx.
Seismic hazards in terms of percent gravitational acceleration,
Primary sensors in inertial navigation are sensors of angular velocity, whose output signals after integration are used for determining the orientation in space, and accelerometers whose output signals after precise compensation of gravitational acceleration and the Coriolis force can be integrated onto the speed and position.
where [a.sub.N] is the Newtonian gravitational acceleration, [??] is the radial unit vector and [a.sub.0] is a constant with dimensions of acceleration.
The new mathematical model tightly couples a range of physical processes present during cosmic reionization, such as gas motion, radiation transport, chemical kinetics, and gravitational acceleration due to star clustering and dark matter dynamics.
G-loading is a factor of acceleration, either in terms offsetting the earth's gravitational acceleration (commonly experienced as 1g "weight") and/or applying other acceleration forces such as turning or (momentarily) entering a climb or initiating a descent.
