1. When the velocity of an object changes, it either accelerates or decelerates.
For an understanding of dynamics, it is necessary to have a knowl-edge of kinematics, which is the study of motion alone.
Dynamics is the study of the ways in which objects behave when they are acted on by forces.
The fundamental problem of dynamics is determining the mo-tion of an object acted on by forces.
Just as there are many different types of forces, there are also different types of motion produced by those forces: linear motion, circu-lar motion, simple harmonic motion.
The next concept is that of the velocity of the particle.
The most basic concept in kinematics is that of the displacement of a particle.
