[@benjamator6700]

Interesting video! Loved the dog that curiously walked over to the pool with the bowling balls.

[@YeanyScience]

it's her pool, she didn't quite understand why I was dropping bowling balls into it

[@underadesk]

Bruce! You have my absolute favorite car! Love the 77-90 wagons so much. I usally watch your videos for their fun, practical, very buildable demonstrations. But at the same time, seeing my favorite ride is a real treat.

[@YeanyScience]

I've always loved the old wagons myself, this on is a Pontiac Grand Safari, all original,

[@areyoutheregoditsmedave]

I discovered this by accident and it’s the most interesting thing I’ve watched in months.

[@andrewseburn]

Nice work as usual. CONGRATS on the TV Appearance. It'll bring some attention that you so adequately deserve!

[@DaftRebel]

I'm glad this channel still exists!

OMG, a wood paneled station wagon. Now I know you are a real science teacher.

[@alwysrite]

what a lot of effort to make this demonstration, least I can say is thank you for your effort

[@holomurphy22]

2:58 we can see the bowling ball has enough angular momentum to continue spinning in the water Probably because it's heavy so it has way more angular momentum than a basketball would. The basketball would stop spinning quite fast due to the interaction with water

[@Mista808]

2:58 Hector the Golden Retriever was looking at the ball in the water like "WHAT IN THE ALIEN EGGS IS GOING ON AROUND HERE?!" 😆

wow.... it's admirable you went through so much trouble to build this wooden track. Thanks for sharing!

[@davebeedon3424]

Nice garage/workshop! Cool experiment---it made me think about roller coaster velocities.

[@jaysonchavez6076]

I like this guy, what I like most is that I’m willing to bet he bought that old early 80’s wood panel wagon brand new and he’s kept it up in mint condition!

[@backyardgarage912]

I think another very interesting thing to mention is that both balls reach that same height in the air once they leave the tracks despite the different velocities/paths when they were on the track. It's another way of showing they have the same energy.

[@WynandSchoonbee]

I really enjoy your clear experiments & demonstrations! Wish we had more teachers with such passion for science 👍😀

[@yassermasood3423]

Good to see you again sir and you are in good shape

[@DanBurgaud]

If I am not mistaken, these "high low tracks" does not change PE or KE as evidenced at 6:32 both balls land at the exact distance away from the track. The time difference is due to the track's length and how PE was converted more into motion.

[@brianhenson6141]

Another nice video!, i like the way you methodically and scientifically do all your video presentations.

[@DaveBaldacchino]

You're an awesome teacher! Always enjoy watching your work :)

[@boumbh]

The last portion of both tracks could be the same, so we would see that given the same end speed, and the same angle of ejection, both balls follow the exact same fall trajectory. The effect would be more interesting in the 6:22 test. Still, these tracks are gorgeous ^^ .

[@TheX2theG]

[@dorianfeisel2945]

Would be awesome to see an actual brachistachrome next to this. If you don't know what it is, there are some great videos here on KZbin (eg. vsauce) . Basically it is the fastest possible way for this ball to reach the end of the track.

[@zara330]

Great video. Also they land in the same spot in terms of horizontal distance away from the ramps. In other words they travel the same distance horizontally since they eject with same horizontal speed.

[@THECHOSENONE-bk7xg]

[@sumitrana3657]

You are superb sir . Thank you so much for giving this to students to clear our concepts

[@petercuthbert4998]

Same energy distributed differently between rotational energy and linear velocity. The slower ball is spinning faster.

[@thetruth156real3]

That’s amazing,,,,,I never realised,,,,,,,,,,,,,,,,,his car is made of the same material as the garage doors.👍

[@dm5331]

great video. i appreciate the comprehensive explanation. also beautiful wagon u got in the background. they don’t make em like that anymore

[@junkmail4613]

Look at the landing spot!!! At different times, BUT landing at the same distance from the end of the ramp!!! AMAZING.

[@attiliobastosguarnieri5416]

Pense grande !! Foi isto que este professor fez !! ! !! Excelente.

[@avba7472]

Is the speed of the ball the same when it exits the track ?

[@timothyaaron8603]

I never knew bowling balls could float. Great educational video!

[@carultch]

Depending on the class of bowling ball, it may either float or sink. Bowling balls are very close to 1 g/cm^3 in density. The heavier class of bowling balls are denser than water. Just about all bowling balls would float in extremely salty water like the dead sea. It's surprising to see this, because you might initially expect a bowling ball to be twice or three times the density of water, since it is known for being a heavy ball.

[@hardrockminer-50]

There was a missed opportunity to explain why (the formula) the compound track resulted in more kinetic energy (speed) being imparted to the right side

[@tylereno3328]

Nice shop! You should do some carpentry videos!

[@ryankc3631]

I get it. He's actually trying to sell that sweet ride in the background. Genius salesmanship.

[@TM-dh2xb]

That station wagon rocks! I want one!

[@w.c.6678]

If the bent track was a smooth curve down then up to meet the same ending points... mindblowing!

[@shyammugal1110]

Sir, I didn't understand exactly how the ball reached the end quickly than the other one. Do reply me sir. Humble request. Thank you

[@vikramnagarjuna3549]

Because initial position and final position is not equal. Based on Galileo inclined experiments it has to reach same height

[@johngaltline9933]

Dumbed down quite a bit, the ball on the straight track uses the full length of the track to pull out all the energy stored, where as the bent track quickly imparts the stored energy in to 'speed' then spends the rest of it's run at a higher speed, losing the extra energy gained by the extra height it had to fall.

[@SteveFrenchWoodNStuff]

Great stuff. I'd love to see a tour of your shop some time.

[@abpccpba]

Great demonstration. Now I understand much better. THK

[@jackevans2386]

Cool ! Love your work.

[@GrimsBar]

Very cool. Surprised you didn't talk about the maximum of the ark matching and why the height was the same for both.

[@Scientist_Albert_Einstein]

[@EvanMoon]

That wood grain American made wagon is awesome

[@jiralishu]

What would happen if the "slow" one actually went as low (close to the ground) as the "fast" one (to convert the same amount of potential energy, but over a longer distance)? What would that look like?

[@highanddryful]

Another excellent video I learn something new every time. Could you do a demonstration with a bell syphon and explain how it actually works in order to syphon water ?

[@YeanyScience]

thanks, this is is my workshop, I hope to do some more videos from there, funny thing is the dog kept trying to climb into the pool

[@phillhuddleston9445]

One thing I noticed is the ball on the higher more gradual track looks like it flew farther so it was likely going faster when it exited the track, the ball on the lower track was losing speed when it exited the track even though it completed the track in a shorter amount of time.

[@PhilBagels]

Which track is more likely to attract a dog?

[@herberar]

Doggo loved the experiment !!!

[@YeanyScience]

I think she was happier to have her pool filled with water

[@lacuentadevideos]

good for you professor, by not forgetting about the little energy conversion into a little sound...
