(DF) Problem 8: In the figure to the right, define The position of P The velocity of P The acceleration of point P a) b) c) oc Se 0

Explanation / Answer

Problem 2:

A particle by definition has mass but no size, whereas, a rigid body has both. As such a particle can be considered to perform either translational or curvilinear motion only while, a rigid body can perform translational as well as rotational motion.

Therefore, the major difference between particle and rigid body kinematics is the absence of rotational effects in particle motion.
