in my opinion, the velocity of any body moving in a circular path is directed in tangential direction. when the velocity is took tangential,its angle formed with reference to the earths radius is 90 degrees. we know that cos90 = 0. therefore,the velocity of the satellites revolving around the earth must be 0 with reference to cos theta. velocity of any satellite revolving around any planet is 0 with reference to cos theta. but this contradicts the fact that " any body with 0 velocity would collide the Earth" stated by Issac Newton. scientists are still researching to get an appropriate answer to this question. - by d.s.rahul
Since, momentum before impact = the momentum after impact. Therefore, A x B = (A + C). v Final velocity, v = A x B/A + C
Force (F) F = m.a and since a = dv/dt thus F = m.dv/dt Momentum (p) p = m.v and since a = dv/dt thus p = m.a.dt By switch dt from R.H.S. to L.H.S we get dp/dt = m.a thus F = dp/dt
Yes. Since the velocity changes all the time, there is an acceleration. The acceleration is towards the center of the Earth. Note that the speed need not change; velocity consists of a speed (magnitude) and a direction, and in a circular orbit, it is the direction that changes.Yes.

Since satellites are in space, and no one has ownership of space, as long as a satellite's orbital takes it over Germany, anyone can have satellites over them.
Zero, since the velocity doesn't change.
The acceleration of the car is 0 m/s^2, since it is maintaining a constant velocity. Acceleration is the rate of change of velocity, and since the velocity is constant, there is no change in velocity and thus no acceleration in this case.
it also revolves
The product of mass and velocity is called "momentum". Note that, since velocity is a vector, so is the momentum.
No, since acceleration is defined as a change in velocity. If there is no change, there is no acceleration.
Since distance (D) equals velocity (V) xtime (T) (D = V x T), then time equals distance divided by velocity or T = D/V. For example, going 20 miles per hour for 2 hours will move a distance of 40 miles. Looking at it the other way, 40 miles divided by 20 miles per hour will equal 2 hours of travel time. PJ
India has launched 56 satellites into space to date. Many of which have since completed their missions and are no longer operational, some have been landed.
