What is particle? What is a \"rigid body\"? What is \"conservative force\"? Give an example of a \"non-conservative\" force? The below relationship embodies what general principle of physical science? T_1 + V_1 = T_2 + V_2 What are the three ways in which a body can move? What is \"kinetics\"? What is \"kinematics\"? What is \"power\"? What is \"work\"? What significance does the date 07 December 1941 have in American history? Solution 2.rigid body is a body which does not under any deformation on application of load 3.conservative force is a force under which internal energy of system remains conserved 4.friction force is an example of non conservative force 6.a body can move either by pure translatory motion or pure rotary motion or with both rotary plus translatory 8.kinematics is the branch of mechanics which deals with motion of body without considering force 9.power is defined as rate of doing work 10.work is defined force multiplied fy displacement in the direction of applied load.
