write the names of types of motion and one examples each.

Explanation:
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.
EXAMPLES OF DIFFERENT TYPES OF MOTION - EXAMPLE
Sr.No. Types of Motion Examples
1 Rectilinear a)March past by the soldiers in straight line. b)Motion of falling objects from certain height
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.
Explanation:
Answer
Normally there are four types of motion:-
• Rectilinear Motion
• Rotational Motion
• Oscillatory Motion
• Periodic Motion
Their definitions -
Rectilinear Motion
Rectilinear Motion also known as a linear motion where its velocity always remains constant and move in a straight line.
example: A ball rolling(it's movement) on a flat ground. You can see its motion is constant and thus remains in a straight line.
Rotational Motion
Rotational Motion is a type of motion that moves around a circular path(a object) in a fixed orbit.
example: The earth's orbit around the sun,
the wheels of a bicycle,the wings of helicopter. They rotate in a fixed orbit. These are rotatory objects.
Oscillatory Motion
It is a motion where an object repeats the same movement again and again,such as to and fro motion in a fixed position.
example: The swinging of a pendulum clock. Where the motion is repeating the same movement in a fixed position.
Periodic Motion
The motion which is repeated in equal interval of time is known as periodic motion.(in physics)
example: Rocking of chair and bouncing of ball.
