merry go round of death

I like how one of the riders got flung out and sailed around 10-15 ft. lucky he didn't hit anything.
 
Marked for potential use in high school math and physics classes. 🙂


edit: ARGGGH! Hey professor of physics - "fake force"? wtf? There's no fake force here. How about Newton's FIRST Law. When your car turns left, there's no "fake force" pushing you to the right that's necessary for Newtonian physics. There's the door pushing YOU to the left. That you're pushing against the door is a simple matter of equal and opposite forces. What's fake about that? Physics professor fail. Southeastern Louisianna University - that explains it.

*edit: third law; not first.

Yea, I've thought that was pretty weird too. I've run into people that try to argue some forces aren't "really there". I generally just leave them be not worth the effort usually...

That's only high school level physics, and perhaps middle school level math. 🙁

I haven't been in high school in 30 years, and at that time the only higher math I had was algebra 1 which was the only higher math I had to take. Since then I've only done basic math. You know that old saying use it or lose it, well I lost it.

uuuhhh...'centrifugal force,' as described in your example, is in fact not a real thing...car changes direction, you do not...

the kids on the merrygoround are victims of 'centripetal' force.
 
They aren't victims of centripetal force. They're victims of insufficient centripetal force, which results in them traveling in a straight line (except in the y-direction, where they accelerate downward at 9.81 m/s². I did no such thing as describe a centrifugal force. When you're going around a bend or spinning in a circle, do YOU push against the car door, or side of the merry go round? Answer is "YES!" This isn't fictitious. The centripetal force is the force acting on you. There is no force acting on you toward the outside of a circle - you're pushing the car door, etc., in that direction. But again, that's not a force acting on you - that's a force of you acting on something else. The mythical centrifugal force is a force acting on you toward the outside.
 
It seems crazy videos like this are becoming more popular.

This video was on liveleak a few years ago. I think my mom even emailed it to me a while back lol.

The physics breakdown is pretty interesting though.

It is a fake force. You aren't pushing against the door, it is pushing against you.

Wow. Just wow. Well, I suppose, since you've been anti-science in a lot of threads in the past that it makes sense that you don't understand even the most basic physics. Isaac Newton would be sad.
