Question

explain different types of motion and explain each of them​

Answer 1

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. 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 a matter that is the atom is in constant motion too. Every physical process in the universe is composed of motion of some sort. The motion can either be swift or slow, but motion exists. It is important that we give due attention to the study of motion because of its importance in the physical world. Motion is mainly described in terms of the following terms:

Distance

Displacement

Speed

Time

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.

$\huge{\red{ \boxed{ \blue{what \: is \: motion}}}}$

The motion of an object shows its changing position, as discussed earlier. But varying objects show varying types of motion. Like for example, a fan is said to be in motion though it is static in its place or a hanging clock that shows motion though it is hanging in its position.

We say that motion is mainly of three types:

Rectilinear Motion, Circular Motion and Periodic Motion .

${ \green{ \boxed{ \orange{Rectilinear Motion}}}}$

In a rectilinear motion, all the objects move along a single line. Some common examples of rectilinear motion are marching soldiers, moving cars, and moving animals. The common thing in all these examples is that they move in a single line .

${ \red{ \boxed{ \blue{Circular Motion}}}}$

Have you noticed the motion of a fan? Some objects are moving even though they are fixed at some position. Here the fan undergoes circular motion. In the circular motion, the objects follow a circular path of motion without changing their position. It is the circular movement of fan that results in cool air. Some more examples of circular motion are the motion of a Ferry wheel, satellites and rotation of planets around the sun.

${ \orange{ \boxed{ \pink{Periodic \ Motion}}}}$

Have you ever seen a clock’s pendulum? It repeats its movement after a specific time. Physically the pendulum isn’t moving. It is fixed to some point, yet it shows motion. This kind of motion that repeats after a specific period of time is known as periodic motion. In the periodic motion, the movement made by these objects is called oscillation. Since it repeats after a fixed period of time, it is named so! Clocks and table fans are the most common examples. Some other examples of the periodic motion are a child’s motion on swings, the motion of the earth around the Sun, the motion of the moon around the earth.
