Class 18 Rotational kinematics and dynamics
Переглядів 772 місяці тому
This class begins by talking about stable and unstable equilibrium and emphasizes the importance of larger base for stability. I show how to do head stand ( or shirshasana yoga) by making bigger base for the body using two folded hand on triangular shape. Then we move to applying rotational equilibrium to solve problems. After that we write equations of rotational kinematics and apply them to s...
Class 17 Torque: computing magnitude and assigning direction
Переглядів 282 місяці тому
This class begins by defining torque and the describes three different ways of finding the value. After that it goes on to write the appropriate sign for the direction of torque. It goes through several examples of calculating value and assigning direction to the the torque. #torque #leverarm #directionoftoque
Class 16 Conservation of Momentum
Переглядів 592 місяці тому
This class starts by giving example of conservation of momentum and then then shows how the principle can be derived. After that it discusses the concepts and problem solving in various cases with examples such as collision of two objects in horizontal direction in two dimension, ballistic pendulum, sliding motion after collision and so on. In these examples we talk how we apply energy and mome...
Class 15 Momentum and Impulse
Переглядів 292 місяці тому
This class starts by defining Momentum and Impulse starting from Newton's second law of motion. Then moves finding impulse from force from time graphs. It includes several examples with conceptual questions. #impulse #momentum #Impulsemomentumtheorem
Class 14 Elastic Potential Energy and Power
Переглядів 302 місяці тому
This class begins by applying conservation of energy to an object moving in a loop and then describes how to include friction or thermal energy in the energy conservation idea with an example. Then we derive the expression of elastic potential energy by using the idea of work done by a variable force. Towards the end of class we introduce power and give some examples. #elasticpotentialenergy #p...

Thank you, came in clutch for physics pendulum report
yes, some part of it.
Can we take stroller for baby?
sir,may we use this for positive matrix factorisation( pmf) model ?
It is about computing uncertainty of random data not matrices.
After calculation, What is the Unit of Measurement for the Calculated Uncertainity
It is same as the unit of your data
Singlehandly saved me on my psychology assignment with this explanation.
nice
Very nice!
Thank you!
The "soa" at the time stamp 4:37 , should have been "soh" like it is written on the title slide. It should be sin = opposite/ adjacent. My bad.
Thanks for this explanation for one of my mechanic engineering labs
Perfect presentation
Great explanation thank you
WHY EXCEL IS COMPLICATE????
Bruh it’s 4:58 am here and I’m going to cry cause I STILL CANT
I would like to acknowledge you for my physics experiment report.
LMAO ME RN
You are good sir, you saved me, God bless
Hello! can you please help me with this question : What is the correct description of any change in a position farther to the left of zero? (as in in a number line ) 1- negative displacement 2- negative position 3- negative distance 4- negative acceleration
Change in position is displacement. It is calculated by subtracting initial position from final. Signs of position depends on your choice of coordinates. Therefore the answer depends on how question is formulated.
@@rawmeshdhungana5978 In the question , there was a picture of a number line . I think its negative displacement?
Very nice presentation, Ramesh jee! Thank you for sharing.
Thank you, Rudra Jee.
