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?

Gravity affects a satellite launch by pulling the satellite towards the Earth during its initial phase of ascent. This requires the rocket to generate enough thrust to overcome gravity in order to reach the desired orbit. Once the satellite is in orbit, gravity continues to affect its trajectory, helping to keep it in orbit around the Earth.


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 due to gravity decreases as the satellite moves farther from Earth because the force of gravity weakens with distance. This is in accordance with the inverse square law, which states that the force of gravity decreases with the square of the distance between two objects.


How does gravity affect a satellite in orbit?

Gravity is the force that keeps a satellite in orbit around a planet. While a satellite is constantly falling toward the planet due to gravity, it also has a forward velocity that causes it to travel around the planet rather than directly downward. This balance between gravitational pull and the satellite's inertia results in a stable orbit. Essentially, gravity acts as the centripetal force that maintains the satellite's circular or elliptical path around the Earth or another celestial body.


Where is the acceleration of satellite directed?

The acceleration of a satellite is generally directed towards the center of the celestial body it is orbiting, such as the Earth for a satellite in Earth's orbit. This acceleration is due to gravity, which keeps the satellite in its orbit.

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

A satellite that is near the Earth is pulled into orbit by its gravity. The satellite is affected by Earth's gravity because of?

The satellite is affected by Earth's gravity due to the gravitational force exerted by the Earth, which acts on all objects with mass. This force pulls the satellite toward the Earth, creating a balance between gravitational pull and its forward momentum, resulting in an orbit. The strength of the gravitational force decreases with distance, but at the relatively close range of low Earth orbit, it remains significant enough to keep the satellite in a stable path around the planet.

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.


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.


When do objects tip over resulting from the torque due to gravity?

Objects tip over when the center of gravity is not directly above the base of support, causing a torque that exceeds the object's stability limit. This tipping point typically occurs when the center of gravity passes outside the object's base of support. Height and weight distribution can also influence an object's tipping over.
