Whereas the centripetal force is seen as a force which must be applied by an external agent to force an object to move in a curved path, the centrifugal and coriolis forces are "effective forces" which are invoked to explain the behavior of objects from a frame of reference which is rotating.

Procedure: The Centripetal force apparatus must be configured so that it will rotate on a vertical axis. Adjust the threaded collar holding the spring so that there is minimum tension on the spring. Set the friction disc so that it ... b) Could a horizontal axis of rotation, rather than a vertical axis be used? Explain why.

Centripetal force is defined as the force necessary to move a body in a circular path and is always directed towards the centre of the circular path.

Thank you, Miss R. Additionally: Thank you very much for responding to our question about centripetal force. We will be trying the experiment. We have one more related question. What then is centrifugal force? and What is the difference between centripetal and centrifugal forces?

Explain that the force that acts in the roller coaster case is a special force called centripetal force. Define it as a force that points towards the center ...

The ISS - and the astronauts - are prevented from being thrown out of orbit (like the water thrown out of the clothes in the spin drier) by the force of gravity. This balancing force is called centripetal force, and keeps the ISS in a closed orbit.

All accelerations are caused by a net force acting on an object. In the case of an object moving in a circular path, the net force is a special force called the centripetal force (not centrifugal!). Centripetal is Latin for "center seeking".
