1.5 Gravitational force The gravitational force on a particle with mass of m can be calculated by F=mg Where g is the gravitational acceleration of a the planetary body or the asteroids. For the Earth, Moon and Mars, g is equal to 9.86 m/s2, 1.6 m/s2, and 3.7 m/s2, respectively. ...
5. Abovethe Earth's surface, the magnitude of the gravitational force on a particle due to the Earth is inversely proportional to the square of the distance ofthe particle from the centre of the Earth. The Earth is modelled as a sphere of radius R and the acceleration due to gravity at...
Gravitation is a study of the interaction between two masses. Understand the concepts of Gravitational Force along with Newton's Law of Gravitation, its formula and derivation and solved examples.
There are four fundamental forces in nature - gravitational, electromagnetic, strong and weak nuclear forces. Strong nuclear force is the strongest fundamental force while gravitational force is the weakest fundamental force.

Based on the data, the team, with the participation of the China Earthquake Administration and the University of the CAS, found that gravitational force released from the sun and gravitational force recorded at ground stations on Earth did not travel at the same speed, with the time difference ...

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 applies a gravitational forceF2on same particle placed at P. The ratioF2/F1will...
Earth InEarth: Basic planetary data Earth’s gravitational field (seegravitation) is manifested as the attractive force acting on a free body at rest, causing it to accelerate in the general direction of the centre of the planet. Departures from the spherical shape and the effect of Earth’s...
