One of the four fundamental physical forces, gravity influences every engineering enterprise humans have ever undertaken, especially in the realm of economics. Being able to calculate the force of gravity and solve related problems is a basic and essential skill in introductory physical science courses...
This study designed, developed and tested a novel, practical, gravity-independent exercise machine, the Constant Force Resistance Exercise Unit (CFREU). A CFREU prototype was designed and built according to National Aeronautic and Space Administration (NASA) hardware and physiological requirements, and...
The radius of the Earth (r)= 6.38 × 106m Acceleration due to gravity (g) = 9.8 m/s2 Universal constant (G) = 6.67 x 10-11N m2/ kg2 Solution: F = Gm1m2/r2 F = ( 6.67 x 10-11) (5.98 × 1024)(2 x 103)/(6.38 × 106)2 ...
An easy example to give is that of two children of different weights sitting at the opposite ends of a seesaw, trying to balance each other. If the children are the same mass, then the resultant force that they create under gravity is the same and they should sit an equal distance away...
Capillarity is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. 6.4.5.8 Viscoelastic forces Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation....
A solid sphere of uniform density and radius R applies a gravitational force of attraction equal toF1on a particle placed at P, distance 2R from the centre O of the sphere. A spherical cavity of radiusR/2is now made in the sphere as shown in given figure. The sphere with cavity now ...
Generally, particles become fluidized when an upward-flowing gas imposes a high enough drag force that begins to overcome the downward force of gravity. For fine Group C particles, as the interparticle forces dominate over the gravity, it is now the interparticle forces that need to be overcome...
When Newton discovered that the acceleration of the Moon is 1/3,600 smaller than the acceleration at the surface of Earth, he related the number 3,600 to the square of the radius of Earth. He calculated that the circular orbital motion of radius R and period T requires a constant inward...
where xcg is the longitudinal distance between the center of gravity and the center of rotation. The mass of the model, m, including the mass of the water filling the inner space of the model, was measured by a weight scale, and it was 37.6 kg. It generated a centrifugal force correspo...
