  • Because these two rings in the Citadel are connected, then the further you are out from the center of rotation, the more centripetal force you will feel.

Examples

  • Now, I'm going to increase the centripetal force by tucking in my arms.

  • The roller coaster relies on centripetal force to keep the cars moving along the curved track.

  • Well, you don't have enough centripetal force, right?

  • But I think scientists like to call it centripetal force because you need to provide a force towards the centre of a circle to make this ball go round.

  • I'm rotating at the equator, and so I must have some centripetal force inward, keeping me going in a circle.

  • By Newton's laws, a particle of mass m in uniform circular motion experiences a centripetal force equal to mv² / r (v is the uniform speed and r is the radius of the circle).

  • During the experiment, we observed how the centripetal motion of the planets keeps them in orbit around the sun.

  • In physics class, we learned that centripetal acceleration occurs when an object moves in a circular path.

Morphology

centripetal = center (semi-transparent) = centri + petal

While 'centri-' suggests a relation to 'center', 'petal' is not a standalone English word, making the connection less direct.

Etymology

Centripetal combines centri- 'center' and -petal 'to seek', so it literally means 'moving toward the center'. In physics this helps you imagine a skater pulling her arms in as she spins, with motion directed inward toward the center.
