Explain centrifugal force and centripetel force ??
Centrifugal force (Latin for "center fleeing") describes the tendency of an object following a curved path to fly outwards, away from the center of the curve. It's not really a force; it results from inertia — the tendency of an object to resist any change in its state of rest or motion. Centripetal force is a real force that counteracts the centrifugal force and prevents the object from "flying out," keeping it moving instead with a uniform speed along a circular path.

Tendency of an object following a curved path to fly away from the center of curvature. Might be described as “lack of centripetal force.” | The force that keeps an object moving with a uniform speed along a circular path. |
Direction | |
Along the radius of the circle, from the center towards the object. | Along the radius of the circle, from the object towards the center. |
Example | |
Mud flying off a tire; children pushed out on a roundabout. | Satellite orbiting a planet |
Formula | |
Fc = mv^2 /r | Fc = mv^2 /r |

Is it a real force? | |
No; centrifugal force is the inertia of motion. | Yes; centripetal force keeps the object from "flying out". |
