Types of Motion
Types of Motion
Consider three moving bodies, such as a moving car, the moving blades of a fan and a rolling ball. Though all the three bodies are in motion, they do not move in the same way. So, objects move in various ways.
Types of motion: There are different types of motion: translational, rotational, periodic, and non- periodic motion.
|
Rectilinear Motion |
Curvilinear Motion |
Transitional Motion | Rotational Motion |
|
1. When an object in translational motion Moves in a straight line, it is said to be in rectilinear motion. |
1. When an object in translational motion moves along a curved path, it is said to be in curvilinear motion. |
1. A type of motion in which all parts of an object move the same distance in a given time is called translational motion. | 1. When an object moves about an axis and different parts of it move by different distances in a given interval of time, it is said to be in rotational motion. |
|
2. Examples are a car moving on a straight road and a train moving on a straight track. |
2. Examples are a stone thrown up in the air at an angle and a car taking a turn. |
2. Examples are vehicles moving on a road, a child going down a slide, and a bird flying in the sky. Translational motion can be of two types, rectilinear and curvilinear. | 2. Examples of objects undergoing rotational motion are blades of a rotation fan, merry-go-round. |
Which of the following are correct ? (a) A car moving on a straight road and a train moving on a straight track is an example rectilinear motion (b) The pendulum of a clock moving between two points is an example circular motion.

10thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
Shivam Rana
7thOne of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.

8thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
