Those who wish to adopt the textbooks are required to send a request to NCERT, upon which soft copies of the books are received. The material is press-ready and may be printed by paying a 5% royalty, and by acknowledging NCERT. [11] The textbooks are in color-print and are among the least expensive books in Indian book stores.

NCF 2005 has been translated into 22 languages and has influenced the syllabus in 17 states. The NCERT provided a grant of ₹10,00,000 to all states to promote NCF in their local language and to compare its current syllabus with the syllabus proposed, so that a plan for future reforms could be made.
Gravity on the Earth's surface varies by around 0.7%, from 9.7639 m/s 2 on the Nevado Huascarán mountain in Peru to 9.8337 m/s 2 at the surface of the Arctic Ocean. [6] In large cities, it ranges from 9.7806 m/s 2 [ 7 ] in Kuala Lumpur , Mexico City , and Singapore to 9.825 m/s 2 in Oslo and Helsinki .
Besides scientific papers and books and popular science literature, Narlikar has written science fiction, novels, and short stories in English, Hindi, and Marathi. He is also the consultant for the Science and Mathematics textbooks of NCERT (National Council of Educational Research and Training, India).
It is a constant defined by standard as 9.806 65 m/s 2 (about 32.174 05 ft/s 2). This value was established by the third General Conference on Weights and Measures (1901, CR 70) and used to define the standard weight of an object as the product of its mass and this nominal acceleration .

Both Brans–Dicke theory and general relativity are examples of a class of relativistic classical field theories of gravitation, called metric theories.In these theories, spacetime is equipped with a metric tensor, , and the gravitational field is represented (in whole or in part) by the Riemann curvature tensor, which is determined by the metric tensor.
