If a body of mass m is in uniform circular motion with speed v and radius r, then the force acting on it has magnitude F = mv2 / r and is directed towards the centre of the circle. This is termed a "centripetal" (meaning "centre-seeking") force.
To decrease the magnitude of the centripetal force, you must therefore either decrease the mass of the body, decrease the orbital speed, or increase the radius of the orbit.
The centripetal force decreases. F= mv^2/r = mGM/r^2
No; "centripetal" implies an inward force.
The centripetal force is equal to the gravitational force when a particular body is in a circle. For a body that is in an orbit, the gravitational force is equivalent to the centripetal force.
no, but rotation can produce centripetal force
Answer It is the force which keeps a body moving in circular motion. Centripetal force is the force that acts opposite to cetrifugal force. Centripetal force is a real force. Centrifugal force is a pseudo-force
The gravitational force IS the centripetal force in this case.

In any circular movement, including driving in a curve, the centripetal force (and the corresponding centrifugal force, which is often considered a "fictitious force") will increase: * When the speed increases * When the radius of curvature decreases
Centripetal force is a force that is required to exist to have a circular motion. Thus the centripetal force can be any force that is able to accomplish this task. Examples of centripetal forces are the gravitational force, the electromagnetic force, the frictional force, or the constraint forces. The centripetal force depends on the system that is involved in be in a spin of a rigid body, or of a planetary motion, etc. Each particular system that requires a rotation or a spin needs to have a corresponding centripetal force.
Centripetal acceleration is proportional to the square of the speed (a = v2/r). Therefore, according to Newton's Second Law, centripetal force is also proportional to the square of the speed.
The centripetal force
Acceleration in circular motion is the acceleration directed towards the center of the circle, known as centripetal acceleration. It is responsible for keeping an object moving in a circular path rather than in a straight line. The magnitude of centripetal acceleration is given by the formula a = v^2 / r, where v is the velocity of the object and r is the radius of the circle.
