Working mass Working mass Working mass, also referred to as reaction mass, is a mass against which a system operates in order to produce acceleration. In the case of a rocket, for example, the reaction mass is the fuel shot backwards to provide propulsion. All acceleration requires an exchange of momentum, which can be thought of as the "unit of movement". Momentum is related to mass and velocity, as given by the formula "P = mv," where "P" is the momentum, "m" the mass, and "v" the velocity. The velocity of a body is easily changeable, but in most cases the mass
N. S. Satya Murthy Indian Academy of Sciences elected Murthy as a fellow in 1975. The Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 1979. He became an elected fellow of the Indian National Science Academy in 1981. He was also a life member of the Magnetics Society of India. The Indian Physics Association has instituted an annual award, "N. S. Satya Murthy Memorial Award" for recognizing research excellence in physical sciences among young scientists. N. S. Satya Murthy Nivrathi Suryanarayanashastry Satya Murthy (5 February 1936 – 8 October 1984) was
