A centripetal force is, by definition, a force that makes a body follow a curved path. So, yes, a centripetal force causes rotation about a point in space.

Can centripetal force produce rotation?
no, but rotation can produce centripetal force
What is the measure of how effectively a force causes rotation?
centripetal force
If the radius of rotation and the mass being kept constant how does the centripetal force vary with the speed of rotation of the body?
Recall centripetal force = m v^2 / rAs m and r are found to be constants then centripetal force F is directly proportional to the square of the velocity of the body
If the magnitude of applied force falls short of required centripetal force then the object will move away from the centre of the circle?
Yes. It would spiral away such that the radius of rotation will increase, until the radius is large enough for the centripetal force to decrease to the applied force. (Centripetal force= mv2/r)
What factors are true about centripetal force?
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.
Centrifugal force is a force that acts perpendicular to the direction of motion of an object and keeps the object moving in a circle?
No, centrifugal force is the force that causes objects in rotation to move away form the center of rotation. The force that keeps objects moving in circular motion is called "centripetal force".
What are some examples of centripetal forces?
Centripetal force is a force that makes a body follow a curved path. An example of centripetal force is gravity making something in space orbit Earth. Mud flying in circles from a tire going down the road is centripetal force.
Is a centrifugal force the same as the centripetal force?
Answer: no..while centrifugal force is about something going away from the center of rotation, the centripetal force means getting pulled towards the center of circle. Answer: Also, the centripetal force is a real force, while the centripetal force is a ficticious force - or a force that only appears in a rotating frame of reference. For purposes of calculation, the magnitude of both forces is the same, and same formulas can be applied: F = ma, and either a = v2/r, or a = omega2 x r.
What is the force that keeps an object moving on a curved path that is directed inward toward the center of rotation?
Centripetal force works opposite tangential acceleration.
What is the tendency of a force to produce rotation is called?
Torque
Is centripetal force a outward force?
No; "centripetal" implies an inward force.
How can you control centripetal force on a roller coaster?
Centripetal force does not exist on a roller coaster or anywhere else. You would more be thinking along the lines of Centrifugal force. This is the force that pushes outwards. For instance, swinging a ball on a string, it is centrifugal force that keeps the ball extended outwards, and if you let go of the string, catapults it outwards. ---------------------------------------------------- In physics, centrifugal (centre-fleeing) force is a fictitious force. It is the reactionary force (Newton's 3rd Law) to the centripetal (centre-seeking) force in a rotational reference frame. In an inertial frame of reference, only centripetal force exists. The magnitude of the centripetal force is calculated as: Fc = mv2/r Therefore, if you want to increase the centripetal force, you can increase the mass of the object undergoing rotational motion, increase the velocity of the object, or decrease the radius of the circle of rotation and vice versa if you want to decrease the centripetal force.
