Question

Hii,

Define motion with example.​

Answer 1

Answer:

Motion is the movement or a proposal for action. An example of motion is waving hand.

Answer 2

$\huge{ \text { \underline{ \underline{✿Answer}}}}$

Motion, in physics, change with time of the position or orientation of a body. ... Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

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. 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.

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.
• 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.
