In physics, apparent weight is a property of objects that corresponds to how heavy an object appears to be. The apparent weight of an object will differ from the ordinary weight of an object whenever the force of gravity acting on the object is not balanced by an equal but opposite contact force. By definition, the weight of an object is equal ...
Archimedes' principle is a law of physics fundamental to fluid mechanics. ... and apparent weight of that object in the water (in Newtons). To find the force of ...
The most common definition of weight found in introductory physics textbooks defines weight as the force exerted on a body by gravity. [1] [12] This is often expressed in the formula W = mg, where W is the weight, m the mass of the object, and g gravitational acceleration.
Weightlessness is the complete or near-complete absence of the sensation of weight, i.e., zero apparent weight. It is also termed zero g-force, or zero-g (named after the g-force) [1] or, incorrectly, zero gravity. Microgravity environment is more or less synonymous in its effects, with the recognition that g-forces are never exactly zero.
The weight of an object on Earth's surface is the downwards force on that object, given by Newton's second law of motion, or F = m a (force = mass × acceleration). Gravitational acceleration contributes to the total gravity acceleration, but other factors, such as the rotation of Earth, also contribute, and, therefore, affect the weight of the ...

TNT's Charles Barkley and Shaquille O'Neal, along with ESPN's Stephen A. Smith, were especially critical of Williamson's weight and conditioning during New Orleans' 133–89 blowout loss to the ...
Likewise, passengers who move in a space station experience changes in apparent weight in different parts of the body. [7] The Coriolis effect gives an apparent force that acts on objects that are moving relative to a rotating reference frame. This apparent force acts at right angles to the motion and the rotation axis and tends to curve the ...
