Sir apki videos dekh kar lagta hai ki koi apna sach me sath me padha Raha hai pata hi nahi chalta ki time kab nikal gya ....so helpful sir ... thank you so much 🌻....and we want more questions from this chapter sir please... Thank you ✨
41:24 -: Kinetic energy cannot be negative because mass can never be negative and if velocity is negative then there is square on velocity so negative velocity changes in positive. Therefore, kinetic energy can never be negative.
Thanks sir this 1shot helps us very much And very interesting thing for me is that I revised this chapter in a shorter period that save my time Once again THANKS SIR 🙏🙏
9:11 Work is a scalar quantity. 41:17 No, Kinetic Energy cannot be negative. 1:01:19 Potential Energy will be the same in both the cases. 1:08:59 (4) Riding a bicycle: Muscular Energy -> Mechanical Energy -> Kinetic Energy (5) Bow and arrow: Muscular Energy -> Potential Energy -> Kinetic Energy
1:01:06 in both the case potential energy will be same as masses of the objects are equal , g is constant in both cases and height is equal in both cases❤
41:16 No, KE can never be negative as even if the velocity is in negative then its square will be positive. Example : v = -2, m = 15kg =1/2 mv² = 1/2 (15) (-2)² =1/2 (15) (4) = 60/2 => 30 J _____________ 1:08:47 4) muscular energy to kinetic energy (KE) 5) muscular energy to KE
9:21 Work is a scaler quantity 41:20 No kinetic energy cannot be negative 1:01:10 potential energy is same in both the cases 1:08:55 Riding a bicycle: Muscular energy is converted into kinetic energy ; Bow and Arrow: Elastic energy is converted into kinetic energy
41:20 kinetic energy can never be (-) because the mass is always positive and velocity can be (-) but the square of the velo.. can never be (-), it's always positive
41:18 No kinetic energy cannot be zero Explanation : Kinetic energy is the energy an object has due to its motion. It's calculated by multiplying half an object's mass by the square of its velocity. Since mass can't be negative and the square of any number is non-negative, kinetic energy can only be zero or positive.
1:01:22 dono mein potential energy same hogi because dono object ki height same he aur 2nd object ka distance zyada he lekin vo pe ke formula me he hi nahi
With this lecture sir i. got full marks on physics thank you sir sir you are great i really like this one shot and this is really helpful for our exam thank you sir🎉

Work is a scalar quantity as the work done is same irrespective of the direction and only need the value or magnitude of F and s.
Example
1st case) when the force is applied to the right direction on an object (the s is also in the right direction then)
Suppose, F = 2N
s = 3m
Work done= Fs
= 2 × 3 => 6N
2nd case) when the force is applied to the left direction on an object (the s is also in the left direction then)
Suppose, F = 2N
s = 3m
Work done= Fs
= 2 × 3 => 6N
Thus we can say Work is a scalar quantity bcoz the work done is same irrespective of the directions.
@EmranBehera bro it's been 10 months nd lookin at ts comment now idek tf is s or F.. had the worst academic downfall fr

Good bro ❤❤❤
1:08:56 Riding a Bicycle = muscular energy - kinetic energy. Bow and arrow = muscular energy-elastic energy-kinetic energy

41:24 -: Kinetic energy cannot be negative because mass can never be negative and if velocity is negative then there is square on velocity so negative velocity changes in positive. Therefore, kinetic energy can never be negative.

No, KE can never be negative as even if the velocity is in negative then its square will be positive.
Example : v = -2, m = 15kg
=1/2 mv²
= 1/2 (15) (-2)²
=1/2 (15) (4)
= 60/2
=> 30 J
