- Mr. Wizard uses a roller coaster to demonstrate centrifugal force. Subscribe now for more science, nature and technology clips from the 1980's Nickelodeon show, Mr. Wizard's World, every week on #WizardWednesdays.
Not even fighter pilots are subject to having to hold on to a bucket of popcorn during "high G" maneuvers. This kid is boss.
That poor boy, but science must go on!!!!
When young Harry Potter was getting off the roller-coaster, I could see a kid who vaguely looked like Ron Weasley.
The boy wizard in an alternative universe, it seems

Mr. Wizard has pull at Six Flags, apparently.
Inertia + centripetal force creates a centrifugal EFFECT (not a force).
Then why does the elastic stretch outwards radially when you swing a ball on it.
yeah..this is wrong ,the cup has the force that's pushing back on the popcorn
It is an inertial force. You don't have to avoid the word "force". It behaves identically to one inside rotating reference frames and if you want to reconcile Newton's laws from within a rotating reference frames, you're going to have problems if you do not treat it as a legitimate force. Your clarification is unnecessary.
@@willoughbykrenzteinburg kind of. Theres no such thing as centrifugal force. Its just inertia with another body exerting a centripetal force redirecting it and keeping it going in a circle
@@RetroRockGamer "Theres no such thing as centrifugal force" is a categorically false statement. It is a thing. It's an _inertial_ force and is defined as such. I've said this already. It's not "kind of" true. It is absolutely true.
I miss Mr. Wizard's World.
Is he dead ☹️
It’s interesting watching these old episodes, because how teachers treated students was different than today. Obviously, Mr. Wizard is a kind man and passion about teaching science, but unlike today, there is no coddling of the kid’s emotions. Today, if the kids said the roller coaster, scared him, the teacher would say something like “you were very brave.” Nope, not Mr Wizard!
Thank you Mr wizard throughout the magnificent years as a great teacher and scholar for protecting such values of alloyed metals that offer such structural support to our beloved core but most importantly thank you for protecting all the elements of the periodical chart for our safe inhabitants of the United States of America of a civilian zone separate from a military zone. Thank you for your continued pursuit to your excellence of freedoms of Education. And thank you for being such an excellent teacher all these years respectfully and sincerely

"Okay get out so the other people can get in"
Hahaha the kid is like "cup" to Mr Smarts Physics Dude
I forgot all about this show. I used to love it growing up. Now I'm trying to find a kids video to explain to my 7 year old step-daughter what centrifugal force is. But it's 2020 and this video doesn't have enough flashing strobes and explosions to hold her attention.
Also look up Adventures in physics with Professor Julius Sumner Miller. Older than Mr. Wizard and on PBS. I loved his show growing up.
It's true, my son thinks these videos are boring because there's no special effects! 🙄
@@smokescreenFromThe6ix The attention span of today's young people can be really annoying - on the other hand, I've always heard that the business of teaching is a matter of continuously adapting and evolving to different learning styles rather than teaching the way you want to, exactly like how science works (IE: revising your assumptions based on the evidence, rather than ignoring evidence you personally don't like).
You may have noticed that just as Christian was getting out of the roller coaster, three of Mr. Wizard's other friends, (Michael, Jason and Stacy) were among those getting in.
Wow! I just noticed that after all of these years!
I always thought Stacy was a boy because of her dress and haircut.
I did notice, looked in the comments to see if anyone else did. It must have been Mr. Wizard Day at the rollercoaster.
And based on circulating episodes, these assistants were likely at the park the same day to conduct experiments. We've seen Stacy's and Michael's experiments in Episode #34 and #36, respectively, on this channel, but Jason's is yet to be uploaded (it could be in Episode #49, which has yet to be uploaded).
That kid was scared shitless 💀
this kids got balls of steel. doesnt make a peep or even look bothered , but then goes "ooh that was scary:" LOL. what a boss!
that's because Mr. Wizard threatened to give him a knuckle sandwich for lunch if he said anything.
@@user-tk1lf5hi6fwas he a prick irl?
Some people are v confused here. Centripetal and centrifugal forces are only subject to the frame of reference you are in
But they do exist.
Doesn’t centripetal force exist in all frames of reference
At last a video that explains the truth about it. I've seen so many videos saying the inertia is the responsible for keeping the water up (wrong) or that the centripetal force is the one (also wrong). Then I found your video. At the end the water "feels"gravity up, being pushed up by centrifugal force. That is the reason !! If there is no force down, the water has no reason to go down....I loved you video....
Nah they were right and you are wrong
Anyone know where this particular Arrow Corkscrew is?
ShinobiTreecko8 Under Red Alert this is Vortex at Calaway Park in Canada it opened here in 1982 as Turn Of The Century.

So on a rollercoaster, if a person urinate's while looping around, will it go in their own face? Or splsh all over? 👀
Interesting
If anyone ever told me to go on a roller coaster by myself I'd be like ":)" and then I'd run like crazy :P
Looked like the old corkscrew from knotts berry farm..
They should´ve probably scripted it
The kid looks like Harry Potter.
it really well i see you threw up on your popcorn.
Haha, "Well you see I think it was actually just the stickiness of the vomit which held the popcorn in place sir, not this "centri fical force" thing"
I got a rick roll add at the end😢
It's centripetal force (centripetal acceleration), NOT centrifugal force (it's center seeking force, not center repelling force).
nickcube4
no its centripetal that keeps the cup from flying off, centrifugal keeps it from moving to the centre
If you swing a ball on a string the ball will "EXERT" a centrifugal force on your hand as a reaction to the the centripetal force exerted by your hand on the ball - basic physics.
hi Mr Zaloom
OK all those kids that had to wait to get on the ride so Jr could have his solo ride? Really? like it’s not gonna get beat up at school🤣 The old man should a told all the other kids you get a free ride today because this young man is performing a science experiment on centripetal force and everybody would’ve learned a brand new word and what it means And not further alienate the kid just saying
I hate to point this out but a rotating mass EXERTS a centrifugal force, it is not subject to such a force; any decent book on physics will confirm this. If an object was subject to both a centripetal and a centrifugal force, a common misconception, these forces would cancel each other out, thus nothing would rotate. Frank Smith.
You fail to state why I am confused.
You are confused because a centripetal and centrifugal force only exist together and only when a mass is accelerating. The centripetal force is the F in Newton's second law while the centrifugal force is the ma.
Thank you for responding. Newton's Third Law states, in effect, that forces go in pairs thus if you have a centripetal force you must have a centrifugal force, however, they will not both be acting on the rotating mass; this is the point I make in my original comment. The formula for the centripetal and centrifugal force is the same since they are equal but act in opposite directions and on different masses.
No they act on the one rotating mass in accordance with Newton's second law.
It is obvious If a centripetal force and a centrifugal force act on the same mass they will cancel each out and equate to no force at all.
No such thing as a centrifugal force... Sigh.
