- motion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

We can define motion as the change of position of an object with respect to time. A book falling off a table, water flowing from the tap, rattling windows, etc., all exhibit motion. Even the air that we breathe exhibits motion! Everything in the universe moves. We live in a universe that is in continual motion. The fundamental particle of matter, t...
We might have noticed that different objects move differently. Some objects move in a curved path, some in a straight path and a few others in a different way. According to the nature of the movement, motion is classified into three types as follows: 1. Linear Motion 2. Rotary Motion 3. Oscillatory Motion
Now let us understand motion clearly with the help of a few examples. 1. Our daily activities, like walking, running, closing the door, etc. involve motion. There is a change of position of the object involved in these activities. 2. The flow of air in and out of our lungs is also an example of motion. 3. The automobiles that carry passengers from ...

The most fundamental concept in physics is motion. Here we will examine motion progressing from its simplest manifestation to more advanced forms, growing our mathematical toolbox along the way.
Go to Lesson Page. In physics, motion is defined as the change in position of an object with respect to its surroundings in a given period of time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, time, and speed.
Kinematics is the branch of classical mechanics that describes the motion of points, objects and systems of groups of objects, without reference to the causes of motion (i.e., forces ). The study of kinematics is often referred to as the “geometry of motion.”. Objects are in motion all around us.
Kinematics is the science of describing the motion of objects. Such descriptions can rely on words, diagrams, graphs, mathematical equations, and numerical data. This Chapter describes all of these representations that are part of our Kinematic model of motion.
Kinematics is a subfield of physics and mathematics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move.
