This lesson starts with a starter on linear velocity before moving on to centripetal acceleration and then linking centripetal acceleration to Newton’s second law to derive an equation for centripetal ...

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 ...

Centripetal force: The force that keeps an object fixed in its circular path is the centripetal force. Moreover, this topic deals with the definition, example and formula of it. Centripetal force is a ...

Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always ...

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

TIM PEAKE:Hi I'm Tim Peake. I'm an astronaut based here at the European Space Agency, in Germany. And from December 2015 to June 2016, I spent six months orbiting Earth on the International Space ...
