Question

Mention types of motion and write, their example:3​

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.

According to the nature of the movement, motion is classified into three types as follows:

1) Linear Motion

Rectilinear Motion – The path of the motion is a straight line.

Curvilinear Motion – The path of the motion is curved.

2) Rotary 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.

3) 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

♣ANSWER:-

Examples of different types of motion - example

Sr.No. Types of Motion Examples

2 Circular a) Motion of satellites around planets. b) Motion of car turning to a curved track

3 Rotational. a) Motion of giant wheel b) Motion of wheels of moving vehicle

4 Periodic a) Motion of simple pendulum b) Motion of Earth on its own axis.

♣DIRECT ANSWER:-

RECTILINEAR, CIRCULAR AND PERIODIC MOTION - EXAMPLE

Rectilinear Motion: Motion of the object in straight line path is called rectilinear motion. For example : Motion of train on track, motion of ants in a straight path,motion of freely falling stone from top of the building towards the ground.

Circular Motion: Motion of object in a circular path is called circular motion. For example: Children playing ringa ringa roses or moving in a circle, motion of Earth around the Sun.

Periodic Motion : Motion of a object which repeats itself after a certain period of time is called periodic motion. For example : Motion of Earth around the sun is periodic as well as circular as it repeats it motion after time of 365 days. Motion of simple pendulum is periodic.Motion of minute and second hand in a watch is periodic.
