how many types of motion and it's definition and its examples
Answers
Answer: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.
Types Of Motion
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:
Linear Motion
Rotary Motion
Oscillatory Motion
Linear Motion
In linear motion, the particles move from one point to another in either a straight line or a curved path. The linear motion depending on the path of motion is further divided as follows
Rectilinear Motion – The path of the motion is a straight line.
Curvilinear Motion – The path of the motion is curved.
A few examples of linear motion are the motion of the train, football, the motion of a car on the road, etc.
Rotatory Motion
Rotatory motion is the motion that occurs when a body rotates on its own axis. A few examples of the rotatory motion are as follows:
The motion of the earth about its own axis around the sun is an example of rotary motion.
While driving a car, the motion of wheels and the steering wheel about its own axis is an example of rotatory motion.
Oscillatory Motion
Oscillatory motion is the motion of a body about its mean position. A few examples of oscillatory motion are
When a child on a swing is pushed, the swing moves to and fro about its mean position.
The pendulum of a clock exhibits oscillatory motion as it moves to and fro about its mean position.
The string of the guitar when strummed moves to and fro by its mean position resulting in an oscillatory motion.
Examples Of Motion
Now let us understand motion clearly with the help of a few examples.
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.
The flow of air in and out of our lungs is also an example of motion.
The automobiles that carry passengers from the place of pick up to the destination possess motion. In this case, the position of passengers is changed from one place to another.
