But depending on your current knowledge and future accidents it might be more useful 😉

true 😅, but if they don’t fall it will have been much easier 🙃

😅 either this is the weirdest autocorrect ever or you had a stroke or I missed a joke 😅

Angular momentum is a measure of an object’s rotation around a point (#spin) 🌪️.

Centripetal force is the force that keeps an object moving in a circular path, always pointing towards the center (#holdingtight) 🎯.

One is about spinning momentum, the other about the force directing that spin.

In this example:

As you shoot the water jet at the skateboard wheel, you are continuously adding angular momentum to the wheel. This increases the wheel’s rotational speed.

As the wheel spins faster and faster, the individual particles in the wheel experience a greater centripetal force, pulling them towards the center of the wheel’s rotation. However, at the same time, due to the increased rotational speed, the particles also experience a greater centrifugal force (which is not a real force but an apparent force observed in a rotating reference frame), pushing them outwards.

At a certain point, this outward “force” (centrifugal effect) becomes too great for the material of the wheel to withstand, overcoming the cohesive forces holding the wheel together, and it starts to expand and eventually breaks.

This being said, I’m not sure if that’s actually correct what I just wrote, so take it all with a grain of salt (as one should do anyway when reading something online…)

Thank you 😊

Gifs are one of the things I missed most from reddit, so I thought I get the ball rolling by adding some gifs and hoping others will follow soon 😀
