The centripetal force
Centripetal force is a force that keeps an object inwards, in the case of circular motion or similar.
The centripetal force which always acts perpendicular to the motion of the object
It's not. If the net force on an object is centripetal, then the object can't move uniformly.
centrifugal and centripetal
No
Centripetal force acts towards the center of the circle of motion.
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".
Centripetal force
An object will move on a circular path if there is a force that keeps it in this circular path - in other words, that pushes it towards the center.
centripetal force
Tending towards the center, according to WordWeb, a dictionary program which compiles definitions from several dictionaries and gives the most accurate (in it's opinion). In terms of physics, i.e. centripetal force, centripetal acceleration, centripetal motion, etc, etc, it refers to the motion of an object in a circular path, or the force which keeps it in such a path. The force is always directed towards the center of the circle as by the definition above.
Basically, the centripetal force CAUSES the circular motion in the first place. In other words, without a centripetal force, the moving object would just go straight ahead.
