1 gravitational force

Fig 4.1 Acceleration produced in the stone is due to the large force of attraction exerted by the Earth It is clear from the above example that it is this force of attraction that holds our complex universe together, keeps the moon revolving around the Earth and holds ..

The orbit of a planet is an ellipse with the Sun at the one of the foci.The line joining the planet and the Sun sweeps equal areas in equal intervals of tim..

Introduction - we are going to identify one of the forces which produces acceleration in all objects on the surface of the Earth irrespective of their mas..

Dependence of Gravitational Force on Mass - According to Newton's law of gravitation, the force of attraction is directly proportional to the mass of the body. Consider two objects of mass m separated by a distance d, then the force between them is ..

>This force is very large and it is this force which keeps the planets in their respective orbits. From the above examples, it is very clear that the gravitational force between two objects of ordinary size is very small, whereas the force is very l..

According to Newton's law of gravitation, the force of attraction is directly proportional to the mass of the body. Consider two objects of mass m separated by a distance d, then the force between them is given by the relation Two Objects of Mass m Separated by a Dista..

>This force is strong, we cannot ignore it. Now let us calculate the force of attraction between Earth and the Sun. The mass of the Earth = 6x10 2 4 kg The mass of the Sun = 1.99x10 3 0 kg The distance between the Earth and the Sun = 15 x 10 1 0 m = 3.541 x 1..

Gravitational Force between two Light Objects - Let us now calculate the force of gravitation existing between two unit masses separated by a unit distance. m 1 = 1 kg m 2 = 1 kg d = 1m G = 6.6734 x 10 - 1 ..

>It is the gravitational force, which produces acceleration in both Earth and the stone. The above relation tells us that the acceleration produced due to the gravitational force is more in the case of the stone as its mass is very small whereas the accelerat..

Gravitational Force between Two Light Objects - Let us now calculate the force of gravitation existing between two unit masses separated by a unit distance. i.e., m 1 = 1 kg m 2 = 1 kg d = 1m G = 6.6734 x 10 - 1..
