( J .3.1) In SJ units, unit of force if> Newton (N). Large units of force are kN and MN. The unit of mass i~ kg and unit of acceleration is m/sec 2 , b.ence force is derived unit. From equation (1.3. 1), I N= I kg-m/sec2 . Thus Newton (N) i~ defined :u. force when applied to body having mass I kg, produce~ an acceleration of I m/sec2. (2) Mass (m) : The mass of the body is defined as the amount of matter contained in it. The unit is kg and is denoted by m. (3) Weight (W) : lt is the force with which a body is attr:ided co the centre of the earth. It is the product of mass (m) of the body and local gravitational acceleration (.g). W = mxg (New Syllabus w.e . f academic year 18-19) (G 12-06) Value or g at sea level is 9.80665 m/sec. rt is usually assumed a.-; 9.81 m/sec2 . The weight of the body changes with elevation but the mass always remains constant. - - --- - ____..'.,- ~ --- ~ -=~=---- ~ Tech-Neo Publications ... A SACHIN SHAH Venture
