Dr. Dinesh Prasad Saklani is the director of NCERT since 2022. [2] In 2023, NCERT constituted a 19-member committee, including author and Infosys Foundation chair Sudha Murthy, singer Shankar Mahadevan, and Manjul Bhargava to finalize the curriculum, textbooks and learning material for classes 3 to 12.

The Binet equation, derived by Jacques Philippe Marie Binet, provides the form of a central force given the shape of the orbital motion in plane polar coordinates.The equation can also be used to derive the shape of the orbit for a given force law, but this usually involves the solution to a second order nonlinear, ordinary differential equation.
The National Testing Agency (NTA), the examination organizer, clarified that the higher number of top scorers was due to 44 of the 67 students answering a physics question incorrectly but still being awarded marks because of a mistake in the NCERT book. [55] [56]
The second quadrant is an e-content which could include e-books, illustrations, Case studies, Open source content, reference links, further reading sources, etc. [12] The third quadrant is about clearing students' queries where students can interact with each other and faculty; any student or faculty can answer a student’s question.
IAT consists of 60 questions: 15 questions each from Biology, Chemistry, Mathematics, and Physics. Total time for answering the test is 3 hours. Questions are of multiple choice type with only one correct answer. Each correct answer is awarded 4 marks. Each incorrect answer leads to the deduction of 1 mark. Unanswered questions are awarded 0 mark.
where = is the reduced Planck constant.. The quintessentially quantum mechanical uncertainty principle comes in many forms other than position–momentum. The energy–time relationship is widely used to relate quantum state lifetime to measured energy widths but its formal derivation is fraught with confusing issues about the nature of time.
She has co-organized two physics education research conferences in 2006 and 2007 and was the co-chair of the 2010 Gordon Conference on Physics Research and Education. She co-chaired the first conference which brought together physicists, chemists and engineers from various engineering departments to discuss the future of materials science and ...
The simplest definition for a potential gradient F in one dimension is the following: [1] = = where ϕ(x) is some type of scalar potential and x is displacement (not distance) in the x direction, the subscripts label two different positions x 1, x 2, and potentials at those points, ϕ 1 = ϕ(x 1), ϕ 2 = ϕ(x 2).
