Again it is apparent that the gravitational forces on the earth that might result in earthquakes all come from the Moon and the Sun. The stretching forces from all the other planets, even if added together, are a factor of 1000 less than that of the Moon and Sun. It's not surprising t...
acoustic signals transmitted between oil -immersed acoustic waveguides [AWG] correlated fairly well [20 to 70%] with daily tidal levels controlled by the sun and moon's gravitational forces on earth. Consequently, it is reasoned, the AWG measurements are also in some sense or degree related ...
We define in physics the four fundamental forces which are the weak force, strong force, electromagnetic force, and the gravitational force. The gravitational force is the force of attraction between all masses on earth. This means that any objects are attracting each other because of the ...
The earth being the larger body will not move perceptibly and therefore the smaller body, if free to do so, will move towards the centre of the earth. This force of gravity acting on the body is called its Weight. It should be understood that not all the forces we meet are ...
For the force below, give what produces it, what object it acts on, its direction, and the reaction force. The gravitational force on you as you stand on a horizontal floor. Use these magnitudes of the forces of gravity at Earth's surface to determine the masses of the obje...

The gravitational forces between the Earth and the Moon cause some interesting effects.The most obvious is the tides. The Moon's gravitational attraction is stronger on the side of the Earth nearest to the Moon and weaker on the opposite side. Since the Earth, and particularly the oceans, is...
analogous to μ (magnetic permeability of space) for magnetic fields is equal to G/S 2 , where G is the universal gravitational constant and S is the velocity of propagation of gravitational forces in free space, which in general relativity theory is frequently assumed to be the velocity of ...
The first evidence that dark matter existed is traced back to the 1930s, but it became even more clear that some invisible mass was acting on the gravitational forces of the universe in the 1960s. FromSalon As the stars continue to merge and grow, the gravitational forces grow with them....
