The motion of the earth about its geographic axis that causes day and night is rotatory motion.In rotatory motion, the lone, around which a body moves about, is passing through the body itself. In a circular motion, the point about which a body goes around is outside the body. An axis is a line around which a body rotates. Does the top possess circular motion? The top spins about its axis passing through it and thus it possesses rotatory motion. Particles of the spinning top move in circles and thus individual particles possess circular motion. “The spinning motion of a body about its axis is called its rotatory motion.” Study the motion of a tap. The Brownian motion of a gas or liquid molecules along a zig-zag is also an example of random motion.”The random motion of gas molecules is called Brownian motion.” This may help you: Equations of motion What is Rotatory motion? The motion of dust or smoke particles in the air is also a random motion. The motion of insects and birds is a random motion example. “The disordered or irregular motion of a body is called random motion.”Have you noticed the type of motion of insects and birds? Their movements are irregular and disorderly. The motion of the toy car on the circular track.The motion of the electron around the nucleus.Examples of circular motion in daily life The motion of the moon around the earth is also an example of circular motion. A bicycle or a car moving along a circular track possesses circular motion. Earth revolving around the sun is an example of circular motion. “The motion of an object in a circular path is known as circular motion.”A toy train moving on a circular track. Read Also: Laws of motion Circular motion Sliding a boy in a straight line is an example of linear motion.In the above diagram, a boy is sliding in a straight line which is an example of linear motion. Airplanes flying straight in the air and objects falling vertically down are also examples of linear motion. The motion of objects such as cars moving on a straight and level road is linear motion. We come across many objects which are moving in a straight line. “Straight-line motion of a body is known as its linear motion.” linear motion Motion is commonly described in terms of: It is logical that we should give due attention to the study of motion. Because of its importance in the physical world around us. Every physical process involves the movement of some sort. Everything in the vastness of space is in a state of perpetual motion. The sun and the stars, too, are in motion.

We move around the Earth’s surface, while the earth moves in its orbit around the sun. In every piece of matter, the atoms are in a state of never-ending motion. We live in a universe of continual motion. Therefore we can define rest as “A body is said to be at rest if it does not change its position with respect to its surroundings. But to an observer outside the bus, the passengers and the objects inside the bus are in motion. For example, a passenger sitting on a moving bus is at rest because he is not changing his position with respect to other passengers or objects on the bus. The state of rest or motion of a body is relative. Surroundings are the places in their neighborhood where various objects are present. So if you want to learn Motion and Type of Motion, You’ll love this post.
