A satellite small enough to be treated as a point particle. Can earth's gravity exert a torque on a satellite about the earth's center?
Torque causes an object to rotate around a specific point.
Torque = force * perpendicular distance
and
Torque = moment of Inertia * angular acceleration.
When a satellite is launched, it is forced up to a specific distance from the earth's center and accelerated to a specific velocity parallel to the surface of the earth. The satellite continues moving in circular orbit.
The force which causes the satellite to move in a circular path is the gravitational force caused by the mass of the earth, mass of the satellite, and distance from the center of mass of the earth to the center of mass of the satellite. This force causes the direction of the velocity to rotate so it is always tangent to the circle.
This force produces the torque which makes causes the satellite to rotate so the direction of its velocity is always perpendicular to the direction of the gravitational force.

How does gravity affect a satellite launch?
İf gravity is high, satellite will be very small due to lifting forces for satellite,otherw mise satellite wll vey big.
What happens to the size of the centripetal force due to gravity acting on the satellite if the satellite moves farther from earth?
The centripetal force decreases. F= mv^2/r = mGM/r^2
Draw a diagram showing the motion of a satellite around Earth is the satellite accelerating?
WikiAnswers cannot support diagrams - sorry. A satellite around the Earth will have an elliptical or (in some cases) a circular orbit. The satellite is constantly accelerating towards the Earth due to the gravity between the Earth and the satellite. However, because of the satellite's tangential velocity, it stays at a relatively constant distance from the Earth.
Why don't satellites crash if gravity is attracting them towards the center of the earth?
Because they are in orbit which means they have enough forward motion to keep them into a state of "Free Fall". A satellite is falling to earth's center due to gravity. But for every inch it falls toward earth, earth move out of it's way by one inch.
What is the value of acceleration due to gravity in space?
The magnitude of acceleration due to gravity depends on the mass of the object toward which you're attracted by gravity, and on your distance from it. There are trillions of different possibilities in space.

How gravity is produced in satellite?
Gravity is not artificially produced in satellites.Whatever (negligible) gravity they have is due to their own mass.
Does satellite has acceleration due to gravity or not?
yes, this ADG helps the satellite to orbit earth. This is the centripital force
Which physical quantity is conserved of an earth satellite?
Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.
What happens to the size of the centripetal force due to gravity acting on the satellite if the satellite moves farther from earth?
The centripetal force decreases. F= mv^2/r = mGM/r^2
Does a bar magnet exert a torque on itself due to its own magnetic field?
electric motors produce torque so in the sense yes
How torque is developed due to alignment of two fields?
Torque is developed by, among other things as well, the magnetic attraction or repulsion of two magnetic fields, contributing through rotational leverage to produce a net torque.
If a satellite is travelling in orbit around the earth and the gravitational force drops to nil what will happen to the satellite?
Without gravity, the satellite will travel in the same direction it was going when gravity went to nil. This is due to the object's momentum, and the satellite will go off into space. And if the gravitation were nil to begin with, there would have been no orbit in the first place. The question is problematic, since planets will always have gravity. Picture a ball on a string that is being whirled around by someone. If the string snaps, the ball continues to move in the direction it was going at the moment the string snapped. It flies off in a tangent, and the satellite will do the same thing if gravity is suddenly reduced to zero.
Is the gravity of earth is because of it rotation?
No - the gravity of Earth is due to its mass.No - the gravity of Earth is due to its mass.No - the gravity of Earth is due to its mass.No - the gravity of Earth is due to its mass.
What is acceleration due to gravity called?
Acceleration due to gravity means the force due to weight of an object which increases due to the gravitational pull of the earth.
Is it possible for the body to have zero velocity and non zero average acceleration?
Yes, satellite orbiting the Earth in a Geo-Stationary Orbit has 0 Velocity relative to a point on the Earth, BUT it experience the 'Pull' (acceleration) of Gravity, which prevents it from escaping its Orbit. The Gravity is LESS than that at the surface of the Earth, but not 0. The feeling of WEIGHTLESSNESS is not due to Zero Gravity, but due to the fact that Object is FALLING through its Orbit. A Person Falling "feels" Zero Gravity.
Why do Satellites travel in a circular path?
Satellites orbit the Earth or other bodies due to a careful balance of their velocity and the gravitational attraction of the body. Essentially gravity pulls them down but their velocity moves then out (Newton's Fist Law of Motion) at the same rate. They keep missing the body they orbit.The path is not necessarily circular since the gravity over the Earth varies with the density of the ground below the satellite. They are also satisfied to be in an elliptical orbit (closer at some times than others). The moon is a good example of a satellite in an almost circular elliptical orbit. comets have wildly elliptical orbits.
