Engineering mechanics : Dynamics Dynamics Branch of mechanics that deals with the motion of bodies under the action of forces (Accelerated motion ) Two distinct parts: kinematics study of motion without reference to the forces that cause motion or are generated as a result of motion Kinetics relates the action of forces on bodies to their resulting motionsME101 -Division IIIK austubh Dasgupta1 Engineering mechanics : Dynamics Basis of rigid body Dynamics Newton s 2ndlaw of motion A particleof mass m acted upon by an unbalanced force F experiences an acceleration a that has the same direction as the forceand a magnitudethat is directly proportional to the force ais the resulting accelerationmeasured in a non-accelerating frame of referenceME101 -Division IIIK austubh Dasgupta2 Engineering mechanics : Dynamics Spac
