Question

What is Motion?Explain its type also.​

Answer 1

Explanation:

There are different types of motion: translational, rotational, periodic, and non periodic motion. Translational Motion. A type of motion in which all parts of an object move the same distance in a given time is called translational 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.

Answer 2

: Required Answer

$\longrightarrow$ The motion means displacement or change in the position of an object over time. It can be described in terms of displacement, distance, velocity etc.

❍ ADDITIONAL INFORMATION

❍ Example of motion

➠ 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.

❍ Types of motion

➝ Linear Motion

In linear motion, the particles move from one point to another in either a straight line or a curved path.

➝ Rotary Motion

Rotatory motion is the motion that occurs when a body rotates on its own axis.

➝ Oscillatory Motion

Oscillatory motion is the motion of a body about its mean position.
