... kilograms (kg), and weight is calculated from W = mg. If the gravitational acceleration (g) is specified in units of m/s2, then the weight is expressed in newtons (N). On the earth’s surface, g can be taken as g = 9.81 m/s2. W (N) = m (kg) g (m/s2) => N = kg·m/s2 FPS System: In the FPS system of uni ...

... reference. In the inertial frame of reference, the outward inverse cube law term is palmed off as being merely the effects of inertia. In such orbits, the inward acting centripetal force is caused by gravity and it exists in its own right irrespective of matters relating to the inertial centrifugal ...

... Calculations shows that the maximum horizontal range of the punt is achieved by kicking it at a 45-degree angle, but such a kick has a hang time -- football terminology for time spent in the air -- almost 30 percent less than the theoretical maximum for a given launching speed. Meanwhile, the maximu ...

THE CORIOLIS EFFECT IN METEOROLOGY - IDC
... The blue arrows represent the tendency to flow towards a low pressure area, the red arrows represent the Coriolis effect. The diagrams are very schematic, to bring out the features that are essential. At the start: air mass, being subject to pressure gradient force, starts flowing from all sides to ...

... component of the tension force is required to balance gravity. As the speed of rotation increases, the angle relative to the horizontal may approach 0° but will never reach 0°. 3. If the gravitational force downward and the normal force upward are the only two vertical forces acting on an object, we ...
