Centripetal force is not a force like gravity, which is there for any object with mass in a gravitational field (such as that of the earth, the sun), but a force which must be present in order to move in a circle.
There is never a situation where you say "aha, this generates a centripetal force", but if something is moving in a circle (and certain types of ellipse) you can say that one of the forces already present (such as gravity, or tension for a weight on a string) is providing the required centripetal acceleration for circular motion.
In practice though, the cheap and dirty trick is just to say the centripetal force is equal to (mass of the moving object x velocity^2) / (the radius of the circle).
What else can I help you with?
What is the define of centripetal force?
Centripetal force is the force that acts on an object moving in a circular path, directing it towards the center of the circle. It is responsible for keeping an object in circular motion instead of flying off in a straight line. Mathematically, centripetal force is calculated as the mass of the object times its centripetal acceleration.
What is the symbol for centripetal force?
The symbol for centripetal force is "Fc".
What do you call any force pulling toward the center of a circle?
That is called a centripetal force.
Ask us of the following is true about centripetal force Check all that apply.?
Centripetal force is the force that keeps an object moving in a circular path. Centripetal force always acts in the direction of the center of the circle. Centripetal force is a real physical force that pulls objects radially inward. Centripetal force is necessary to maintain circular motion.
What happens when speed of centripetal force is doubled?
If the speed of the centripetal force is doubled, the required centripetal force also doubles to keep the object moving in a circular path at that speed. The centripetal force needed is directly proportional to the square of the speed, so doubling the speed results in a quadrupling of the centripetal force required.
How do they affect the centripetal force?
If an object moves in a circle, the centripetal acceleration can be calculated as speed squared divided by the radius. The centripetal force, of course, is calculated with Newton's Second Law: force = mass x acceleration. Therefore, the centripetal force will be equal to mass x speed2 / radius.

Is centrifugal a force?
The centrifugal force is an apparent (ficticious) force, caused by a rotational movement. The amount of the apparent centrifugal force can be calculated by the same formula as the amount of the real centripetal force.
How centripetal force equals to gravitational 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.
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.
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.

How does centripetal force affect 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.
What keeps an object in centripetal motion?
