No Submission will be entertained after 24 Hrs Q9 CO1 Q 10 A one line answer to the question “Why artificial satellites remain in orbit and do not fall to earth ?” would be that they are always falling but are also constantly moving forward due to the momentum they get during launch along the tangential path in the form if kinetic energy. Since, there is nothing but vacuum in the outer space to restrict the motion of the satellite they always move at a constant velocity. The tangential component of this velocity along the pulling force of gravitation imparts a centripetal acceleration to the satellite making the satellite to revolve along the earth. The distance at which the satellite remains during the revolutions remains constant and the path travelled by it is known as orbit.

No Submission will be entertained after 24 Hrs CO1 This centripetal acceleration imparts centrifugal force which is balanced out by the force of gravitation and the satellite attains the state of equilibrium. And the satellite remains in the same orbit forever unless the velocity is changed. Gravitational Force = Centrifugal force GMm/r^2 = m(V^2)/r V = sqrt(GM/r) Therefore if is safe to say, that orbits are dedicated to particular velocities.
