F= mv^2/r
here:
m= mass of the object
v= linear velocity of the object
r= radius of the circular path
This is the mathematical equation for both, the centripetal as well as the centrifugal force. Hence mathematically they are equal. But they act in opposite directions. Centripetal force pulls any object undergoing circular motion towards the centre, whereas centrifugal force tries to keep the object away from the centre. Centrifugal Force actually is a Pseudo force.

The centripetal force is the force needed to move an object in a circle at constant speed. Hence it is a force requirement, not a physical force in its own right. Any physical force (gravity, electrostatics, tension, friction, etc.) can be used to supply the centripetal force. The term centripetal force comes from the Latin words centrum ("center") and petere ("tend towards").
Centrifugal force (from Latin centrum "center" and fugere "to flee") is a term which may refer to two different forces which are related to rotation. Both of them are oriented away from the axis of rotation, but the object on which they are exerted differs.
* The reactive centrifugal force is the reaction to the centripetal force. This is equal in magnitude to the centripetal force, directed away from the center of rotation, and is exerted by the rotating object upon the object which exerts the centripetal force. As it is an actual force, it is always present, independent of the choice of reference frame.
* The fictitious centrifugal force appears when a rotating reference frame is used for analyzing the system. The centrifugal force is exerted on all objects, and directed away from the axis of rotation.
Both of the above can be observed in action on a passenger riding in a car. If the car swerves around a corner, the passenger's body pushes against the outer edge of the car. This is the reactive centrifugal force, which is called a reaction force because it results from passive interaction with the car which actively pushes against the body.

If a force is applied laterally (perpendicular) to the velocity of a body and always pointed to ward a fixed point, the body is in circular motion. The force is called centripetal force.
By Newton’s third law, the object which is exerting this force experiences an equal but opposite force. This force is called centrifugal force.
If we revolve a stone along a circular path, the force which pulls the stone toward the center of the circle is called centripetal force. The force experienced by our hand is centrifugal force.
This is the definitions of centripetal and centrifugal force in Physics. Note that the two forces do not act on one and the same body.
But some uses the name centrifugal force in another sense which is of course is not correct if we consider the centrifugal force as a reaction force. Because of this there are many misconceptions among many.
Circular motion is non inertial frame (accelerated motion). In order to change it to inertial frame of reference, in principle we apply a force called inertial force opposite to the force which causes the acceleration.
Thus to change the circular motion to linear motion one should apply a force opposite to that of the centripetal force on the object in circular motion. (Now the two forces act on the same object). This force is called inertial force. As this force is also acting away from the center some call this is as centrifugal force and it is prevailing in engineering studies. However this practice has to be stropped to avoid confusion.

Centripetal force is the force which pulls a body or particles towards the axis of its circular path.
Equ: F=m(v^2)/r, r being the radius of its circular path measured from the axis of rotation.
This equation is similar to F=ma, where you can equate a=(v^2)/r
Please take note that there is NO such force as centrifugal force.
For example, you can feel that you are being pushed outward to the left side of the bus while it is making a right turn.
Reason: you have mass, and before the bus turns, it is moving in a straight line. So do you. When the bus is just making a turn, your body has not turned. According to Newton's first law of motion, your body is reluctant to turn due to inertial.

Both are forces involved in circular motion.
While the centipetal force is directed inwards towards the centre the centrifugal force is directed outwards away from the centre.

centripetal force is a force that moves inward. centrifugal is the opposite of centripetal force.
