If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.

Is torque produce in satellite due to gravity?

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.


The force of gravity is responsible for changing the what in which a satellite moves?

The force of gravity is responsible for changing the velocity of a satellite, thus affecting its path or trajectory in space. This force influences the satellite's speed and direction, causing it to move in an elliptical orbit around a larger body such as a planet or a star.


Is the satellite accelerating?

Yes, the satellite is accelerating because it is revolving around our earth and in a circular motion so its velocity changes every second so it is accelerating.A2. No, the satellite is not accelerating. Acceleration is defined as the rate of change of velocity. But, its velocity is constant. The centrifugal effect is exactly balanced by the pull of gravity (assuming a circular orbit).But a nice question. The net acceleration between these forces is zero.


Why does an orbiting satellites speed remain constant?

The satellite will not change speedbecause the gravity of the earth is a perpendicular force which only affectsdirection and not speed. Parallel forces must beapplied in order to change speed, butperpendicular forces only change direction.


Is the critical velocity equal to orbital velocity of satellite?

Balance of force of gravity by centripetal forceYes, for any given orbital radius (r) only one velocity will give stable orbit, this is called the critical velocity.Pick your orbital radius and satellite mass (m)Use Gmm / r2 to calculate gravitational force (f),then find velocity from : v = sq root ( (r * f ) / m)

Does the force of gravity do work on a satellite when it is in motion?

No, the force of gravity does not do work on a satellite when it is in motion because the direction of the force is perpendicular to the direction of motion.


The force of gravity is responsible for continuously changing the what of a satellite?

The force of gravity is responsible for continuously changing the velocity or speed of a satellite as it orbits around a larger body, such as a planet or a star. This change in velocity helps to maintain the satellite's orbit and keep it in motion around the larger body.


Is there any point along the path of projectile where velocity and acceleration vectors are perpendicular to each other?

Using the term "trajectory" implies that the acceleration you are concerned about is due to gravity. Gravity will always be perpendicular to the surface. Unless the trajectory begins perpendicular to the surface, it will never change to become perpendicular and the velocity will never be in a direction parallel to the acceleration. If it starts perpendicular to the surface it will start and remain perpendicular. Of course if you have another force acting on the object - such as wind - the component of the velocity vector parallel to the ground could be reduced to zero and at that point the only remaining component of the velocity vector would be that perpendicular to the ground and parallel to the acceleration. Likewise if the object is being propelled by an engine or rocket, the trajectory could be parallel to the force any time the acceleration vector became parallel to the velocity vector.

Why There is no work done when satellite rotate around earth?

With satellites, the object is not to escape Earth's gravity, but to balance it. Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going.This is approximately 17,000 mph (27,359 kph) at an altitude of 150 miles (242 km). Without gravity, the satellite's inertia would carry it off into space. Even with gravity, if the intended satellite goes too fast, it will eventually fly away. On the other hand, if the satellite goes too slowly, gravity will pull it back to Earth.At the correct orbital velocity, gravity exactly balances the satellite's inertia, pulling down toward Earth's center just enough to keep the path of the satellite curving like Earth's curved surface, rather than flying off in a straight line.

Gravity is the reason that the planets stay in orbit around the sun?

It is half the reason, at least. Gravity is the force pulling the planets towards the sun, but they also have a velocity working perpendicular to it. With the velocity alone, the planets would fly off into space. With gravity alone, the planets would be pulled into the sun.


Inward and outward forces when a satellite is orbiting Earth?

GRAVITY!!!!


The force of gravity opposes what other force?

The force of gravity opposes acceleration away from the source of the gravity. This is expressed as "centrifugal force" or the perpendicular component of a tangential velocity. The balance between these keeps the planets in orbit around the Sun.


How motion of satellite similar to the motion of an object in freefall?

A satellite is in free fall. When the only force acting upon it is gravity, it reacts freely to this gravity, accelerating towards Earth. That is to say, instead of going in a straight line, the velocity vector changes direction, towards Earth. If the satellite is fast enough to be in orbit, it will never actually fall on Earth; but the velocity vector changes all the time.


What is the effect of gravity on velocity?

Gravity affects velocity by changing the acceleration of an object. As an object falls, gravity accelerates it, increasing its velocity. Without gravity, an object would move at a constant velocity.
