CHAPTER 5

KINEMATICS OF PARTICLES

5.1 The Concept of Kinematics of Particles
Dynamics includes:

i) Kinematics: study of the geometry of motion. Kinematics is used to relate

displacement, velocity, acceleration and time without reference to the cause of
motion.

ii) Kinetics: study of the relations existing between the forces acting on a body, the mass
of the body and the motion of the body. Kinetics is used to predict the motion caused

by given forces or to determine the forces required to produce a given motion.

• Rectilinear motion: position, velocity and acceleration of a particle as it moves along
a straight line.

• Curvilinear motion: position, velocity and acceleration of a particles as it moves

along a curved line in two or three dimensions.
