Sir, in the first explanation... You forget to mention the effect of friction, which is even lower in case of rolling motion... Mass is not much effective here... Because anyone can easily jump over a flat wood of similar mass, kept parallel to ground... I hope everyone can understand it.
Indeed true and if you fix the same skateboard on a pole with rollers not touching the ground (means skate would remain still) then jump is possible due to friction.
I am an IT professional still I watch your videos for fun. Had we gotten this type of education then an average student like me could have also cracked IIT. But great to see students are getting practical knowledge about concepts which will make them love the subject.
@@AF58203 I work in Information Technology (IT) Sector and i am not an IITian as I had also mentioned in my comment that I would have cracked IIT if i would have got teachers like him
Sir there is query in first illustration what if we put skateboard in horizontal form bkoz first you put the skateboard in vertical form . I think if we put skateboard in horizontal form then anyone can cross your border line . Sir is this possible 🤔
Jab hum skateboard ko vertical rakte hai tab skateboard ke wheels roll kar sakte hai, matlab hamare jump krne pr skateboard peeche jaa sakta hai. Lekin jab hum horizontal rakh denge tab wheels roll nhi kar payenge ( fir skateboard normal cheezon ki tarah kaam karega jese koi brick) tab hum jump kar paayenge. Ok?
Guru ji Ager ✌ aap jise teacher hote to Padhne Mein bhut maja ata... 🖤🖤🖤 aap ke padhne se sara Sara concept clear ho jata h 🖤.... गुरु जी को कोटि कोटि नमन.... ❤
Trust me sir ! The way you taech can make any avg student scholar / deeply understand and connect with science ...rather producing robots that aim to score high marks in exam...
Sir aap tho kamaaal hai Kyunki men Kerala se hu aur muje hindi uthna nehi aatha aur aap ka sikkane ka style se muje physics samaj aa raha hai Thank you From Kerala❤❤
Hi there! The concept is great but I think the low mass explanation is a little inaccurate. The role is of the friction. If he kept the skateboard perpendicular to the line of jump, then the jump would have been possible as the friction would be out of line with the rolling friction of the wheel. If I am wrong then please correct me! @scienceandfun
The real definition is that , lower the mass more the acceleration as compared to greater mass when same f is applied. In this case if you put skateboard perpendicular then you achieve that jump as wheels won't moves..but in case of vertical the wheels will moves and reduce friction and according to law its acts.
सर मैं उत्तर प्रदेश पुलिस में सेवारत हु। फिर भी स्टोरी में जो आपकी वीडियो आती है उनको लगातार देखता हूं ।आज इस शार्ट वीडियो को देखकर चैनल भी ससक्राइब कर दिया। आपका सिखाने का तरीका गजब का है।जय हिंद।
I have completed my 12th from commerce this year only and now studying fir ca But I like to see ur videos Really nice teaching 😊😇🥰 Now I understand why they say every action has an equal and opposite reaction 😅😅
Mass in not playing the role but the frictional force, here the reaction force is contact force(friction+normal). As here friction becomes low by making contact area less with the use of wheel, it is very much clear that there won't be satisfying force in forward direction to achieve that length jumped by sir. Have fun have physics 😀😀
@@GauravSharma-je4rj But, think that if there were no wheel, only upper part, you can easily jump. Mass to hamne aur reduce kar diya but friction badh gya, kyunki coefficient of friction badh gya. Conclusion: Mass is not alone which increases the friction, but the friction coefficient. P. S : Here, wheel hamne hta diya so, Mass decreased and friction increased.
@@GauravSharma-je4rj agar mai is skateboard se hlke kisi wooden board pe khade ho kr krunga, to bhut age jump kr skta hun. Kunki wooden board fix rhega sur sari force hme transfer ho jaegi. Yahan *law of conservation of mass and energy ka concept hai* . 💯💯
Hatts off to you sir , koi to hai jo aajkal mei bacchon ka science and pdhaai mei interest bnane k liye hard work kr rha hai ,warna aaj kal to bachhe itne galat influence ho rhe hain ki sab vlogger ya gamer hi banna chahte hain
Tab bhi nhi Jeet pata Ncz sir jamin se kr rhe hai aur tu skateboard ko horizontal rkh kr jump toh maar leta lekin sir se kam Tyre ghumega nhi lekin board earth se juda nhi hai But well played bro
"one of the best thing about dude is that he never takens credit for himself when he achieves something. He always respecto us,the audience, and his team, and he is always polite in all of his videos. Wey congratulate ourselves on this achievement. More to come and everything to come"
Skate board ko horizontal rkhlo fir centre m khde ho kr challang maaro.(skate ke centre of mass pr vertically force apply hone pr skate board nhi hilegi.) Thank U.
What if we put the board horizontally rather than vertically and then jump from it ? The statement was to jump from the skateboard and cross the line right but sir didn't said us that in which position we need to keep the board ...
Aabhi 10 PM ho rhe h or me akeli hi bethi bethi has rhi hu...or me itni jayada bhot dino baad hasi hu....aapka video dekh kr sir...Thanks for making me smile...😂🙂
