This formula is called Newton's law of gravitation. The quantity G is called the gravitational constant; it is evidently the force of attraction between two particles each of unit mass at unit distance apart. Th
by providing two supporting rods 22-1,22-2 on which the substances 21-1,21-2 having known masses are mounted at the tip ends so as to face to the gravity direction of the heavenly body and also providing an angle detector 25-1 to detect the rotating angle of the rotary shaft 24-1....
The value of g sometimes appears in the definition of the units of measurement of physical quantities (e.g. force and work). For this purpose a standard value is arbitrarily defined, g=980.665cm/sec2, which is very close to the value at latitude 45°. Show moreView chapter Book 1967, ...
InNewton’s law of universal gravitation, the attractiveforcebetween two objects (F) is equal toGtimes the product of their masses (m1m2) divided by the square of the distance between their centers (r2); that is,F=Gm1m2/r2. The value ofGis (6.6743 ± 0.00015) × 10−11m3kg−1s...
fields such as electric and magnetic fields, the gravitational field also has direction. Hence, it is a vector field. The gravitational field is measured in terms of gravitational field strength having a unit - Newtons per kilogram. This field force is always attractive and has an infinite ...
The force of attraction that tries to pull two masses together in the universe is termed as gravitational force of attraction. It never pushes the two masses apart. Answer and Explanation:1 The gravitational force is the force of attraction between two bodies which is inversely proportional to sq...

The magnitude of the field at a particular point is the gravitational acceleration (in the direction of the massive body) that would be experienced by any object at that point; this is equivalent to the force that would be experienced by an object of unit mass at that point. A ...
