Outstanding And. No teacher seen ever like you. You're study material is awesome and incomparable

[@hirenm1122]

Mind Blowing. SIR. Bachho aur hamare jaise kau, samjane me aap bahut mahenat karte ho. Maja aa gaya. Aap jaise padhte hao, Physics me Interest aa jata hai.

[@dhoombalebalam2865]

Sir ji aap ki baat hi alg he jitni taarif kre km rhegi

[@pratikacharya5065]

Well understood...things are more clear after this lecture. THANK YOU WIFISTUDY

[@hirenm1122]

Wah Sir.. Mein 27 saale ke baad GRAVITY padha raha tha. Aap Badhiya ho.. Maja Aa Gaya.. pdhate padhte itna hasa. Kyunki, aap bahut badhiya padhate ho. Maja aa gaya. Thanks Jabardast Padhate ho. School ke din yaad gaye.

good effort... its helpful. now let's see in exam, what happened ?

[@mdsaquibsalim2368]

Bahot achaa padhaate ho aap sir✌

[@pallaviparashar1189]

There is a lot of difference between 2nd and 3rd law, how can be say that conservation of momentum work as 3rd law (in rocket)

[@Spiritual_line_6502]

There are two principles at work here: Newton’s Third Law of Motion and the conservation of momentum. Newton’s Third Law states that for every action, there is an equal and opposite reaction. If you push against a wall, the wall pushes back against you with the same amount of force. When you’re sitting on a skateboard and you throw a ball, you move in the opposite direction. This, by the way, is exactly how rockets work. They are designed to keep throwing stuff-ignited propellant, in this case-out one end. The rocket responds by moving in the opposite direction. If you loaded your skateboard up with dozens of balls and kept throwing them, one after the other, you could propel yourself some distance across the floor. Running out of balls would be the same as running out of fuel! Another way to look at it is to keep in mind the fact that momentum must always be conserved. Momentum is a property of moving objects that comes from multiplying together the mass and velocity, mv. When we say momentum must be conserved, what we mean is that a system’s momentum at one time must equal the total momentum at a later time. On the skateboard, your momentum is initially zero because you aren’t moving. When you throw the ball, it achieves a momentum of mbvb (wheremb is the ball’s mass andvb is its velocity). To keep everything balanced, your momentum must exactly balance the ball’s to keep the total momentum at zero.

Thank you sir for providing classes I am from South India and I came to know about Wi-Fi study for not more than one month I am seeing your strength of material classes in those sometimes you tell about the live views not more than 200 and get disappointed but after you upload the video your video is seen by thousands and even lacs of people some people cannot connect to live but they see after the video is uploaded it might be any reason they don't have proper internet connection or they don't have time Please don't get demotivated Thank you sir
