Centripetal and centrifugal forces are central to circular motion, but they're not the same. Discover the differences between ...

When you swing a ball on a rope in a circle above your head, what keeps it moving in that circular path? This applies to any object moving in a circle, not just a ball on a rope - the force and ...

Vertical circular motion is a special type of circular motion in which the forces acting on an object change as it moves along a vertical loop. Specifically, the normal force varies throughout the ...

A couple of commenters expressed concern over the use of centrifugal force after my rant on the use of the word force. So, what is the deal with these two terms? Are they ok to use? Are they real ...

We are talking about Centrifugal and Centripetal forces using a tornado as an example. Centripetal force is a force that keeps an object moving in a circular path, this force points TOWARDthe center ...

We solve for centripetal acceleration, centripetal force, and tangential velocity. In this Closer Look segment on circular motion, we investigate circular motion and solve for centripetal acceleration ...

movement or rotation of an object along a circular path is called \keypoint{circular motion} to describe a circular motion, we can use \emph{angular quantities}, which turn out to be more useful than ...

Polar orbits take the satellites over the Earth's poles. The satellites travel very close to the Earth (as low as 200 km above sea level), so they must travel at very high speeds (nearly 8,000 m/s).
