discuss some salient features of gravitational force
Answers
Explanation:
Gravitational force is the pull of an objects towards itself. we are able to move down wards on earth because of gravitational force. If there will be no gravitational force we will move upwards not dowards.
Answer:
Explanation:
Following are the salient features of gravitational force:
(i) It is always an attractive force.
(ii) It is independent of the medium between the
particles.
(iii) It holds good over a wide range of distances (i.e.,from interplanetary distances to interatomic distances).
(iv) It is an action-reaction pair i.e., the force of attraction exerted by body A on body B is equal to the force of attraction exerted by body B on body A. However, the acceleration of the two bodies will not be equal.
(v) The gravitational force between two particles
is independent of presence or absence of other particles.
(vi) The total gravitational force on one particle due to number of particles is the resultant of forces of attraction exerted on the given particle due to individual particles, i.e.,
It proves that the principle of superposition is valid.
(vii) It expresses, the force between point masses.
(viii)It is a conservative force, i.e., the work done in moving a particle once aro und a closed path under the action of gravitational force is zero
