Once an object is set into motion in a given direction it will continue in that direction unless a force prevents it from doing so. If you swing a ball around and around on the end of a string, it goes in a circle at the end of the string. The thing that keeps the ball from flying off is the string pulling on it. If you let go of the string the ball will sail off in a straight line in the direction it was moving at the moment you release the string.
The ball wants to go in a straight line, the thing that prevents that is the string pulling on it. The string is exerting a centripetal force on the ball preventing it from flying away.
Just like the ball, a satellite rotating around the Earth would fly off into space in a straight line if something weren't pulling it back toward the Earth. Earth's gravity is exerting a centripetal force, pulling on it, preventing the satellite from sailing away.

What provides the centripetal force that keeps objects in orbit?
Centripetal force wants to move something towards the centre. So in a satellites case that would be the Gravity of the Earth. If you had a rock tied to a string you were spinning around, the Centripetal Force would be the tension in the string acting towards the centre.
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
How does the centripetal force act on a satellite?
Centripetal force makes a satellite orbit a body.
What is the force that causes the earth to orbit the sun?
GRAVITY!A2. Centripetal force. The velocity of the satellite around the earth causes centripetal, force which balances with the gravity, holding it in a circular orbit around the earth.
Why an astronot in orbiting satellite has a feeling of weightlessness?
the net force on bodies in stable orbit is nil, the force of gravitational attraction , is balanced by the centripetal force of velocity in a circle. . example, any orbit radius ( if orbit time not important) choose your orbit radius, calculate force of gravity, tailor velocity to produce balancing centripital force . f=((G*m1*m2)/d^2) force of gravity f = m2 *( v^2/d ) centripetal force G = newtons constant m1 = earth mass m2 = satellite mass d = orbital distance

How does weightlessness occur?
When a force is present to oppose that of gravity. eg > Upthrust on a body in a liquid (body in a swimming pool) Centripetal force ( orbiting satellite or space station)
What effects gravity and centripetal combined on the same orbiting path?
I'm not sure exactly what you are asking, but centripetal force is just a name given to any force that causes circular motion. Swing a rock on the end of a string and the string tension is the centripetal force. Drive a car around a flat circular track and the friction between the tires and the road is the centripetal force. Put a satellite in orbit and gravity is the centripetal force.
What is a force that holds a moving object in a circular path is called the?

The centripetal force decreases. F= mv^2/r = mGM/r^2
A force that holds a moving object in a circular path is called the?
A force that holds a moving object in a circular path is a "centripetal force". In the case of an orbiting planet, moon, artificial satellite etc., the mutual force of gravitation between the orbiting body and the central body is the centripetal force.
How does the centripetal force act on a satellite?
Centripetal force makes a satellite orbit a body.
What is the force that causes the earth to orbit the sun?
GRAVITY!A2. Centripetal force. The velocity of the satellite around the earth causes centripetal, force which balances with the gravity, holding it in a circular orbit around the earth.
When a body moves in a circle how force takes part there?
For circular motion to occur, there must be a centripetal force( a force that is always directed towards the centre of the circle). The centripetal force is defined as F = mv2/r Where F is the centripetal force, m is the mass of the orbiting body, v is the velocity of the body, and r is the distance to the centre of the circle. If you whirl a conker above your head, the centripetal force is provided by the tension of the string. For a planet orbiting the sun, the centripetal force is provided by gravity.
What direction of the gravitational force and centripetal force on a satellite?
The gravitational force on a satellite is towards the center of the Earth. The gravitational force IS the centripetal force is this case, so the centripetal force pulls the satellite towards the center of the Earth. There is no balancing force that pulls the satellite outwards (if there were, it wouldn't accelerate, i.e., change direction).
Centrifugal force is the force that?
Centrifugal force is the outward force of a rotating object. The opposite force is the centripetal force which maintains the object in it's rotational position. In the case of an orbiting satellite it's rotational speed (revolutions per time period) creates the centrifugal force required to overcome the gravitational pull (centripetal force) of the body it is orbiting. ================================== The first answer is a neat, tidy, well-written summary of perhaps the most popular misconception in all of elementary Physics. Centrifugal force is a concept made up to account for the sensation of force that we perceive when we move in a curve. There need not be any outward force on a rotating object, and in general there is none. Centripetal force is real. It's the force required to bend the path of a moving abject away from a straight line. There is no outward force on an orbiting satellite. No force is required, and none exists, to 'overcome' the centripetal gravitational pull. In fact, if there were a force that overcame the gravitational centripetal force, then the forces on the satellite would sum to zero and it would travel in a straight line.
