Question

Conclusion of types of motion

Answer 1

Answer:

There is translational motion which means motion in a straight path

There is rotational motion which means motion in circles

Answer 2

All of us know that all living things show movement. The movement in case of animals can be easily seen. The movement in case of plants is very slow and is hardly visible. Among non-living things ,the air shows movement when it blows hard.

“When the position of a body with respect to its surroundings, changes with time, the body is said to be in motion”.

 

6 Types of Motion :

Translatory motion : The motion in which all the particles of a body move through the same distance in the same time is called the motion of a translation. For example A car or a train moving along a road, a ball rolling on the ground, a girl sliding down a slope, pulling out a drawer of the table, firing a bullet from a gun, a stone hurled form a catapult are some of the example of motion of translation.

Circular motion : The motion in which a body moves about a fixed axis without changing its position is called the Rotatory motion or Circular motion. For example A spinning wheel or charkha, a spinning top, a potter wheel, a ceiling fan, the earth revolving around the earth.

Oscillatory motion : Some objects move as a whole, to and fro or back and forth, along the same path without any change in shape. The motion of such objects is called the oscillatory motion. For example the needle of a sewing machine moving up and down, the piston of a motor car, the pressing cylinder of a juice machine at a fruit seller shop etc all perform oscillatory motion.

Vibratory motion : The motion of an object where the moving object undergoes change in shape or size. For example all the musical instruments produce vibratory motion. Even during breathing, when our chest expands or contracts, the motion is vibratory in nature as all the points on the chest do not move out equally.  

Periodic motion : A repetitive motion which repeats itself after a fixed interval of time is called the periodic motion. For example The piston of a motor car engine running at a constant speed. The swinging pendulum of a wall clock, Heart of a resting person beating 72 times in a minute etc.

Uniform motion : When a body covers equal distances in equal intervals of time along a same straight line, the body is said to be describing uniform motion. For example a flying aeroplane in a particular direction at a constant speed, a train moving straight in a particular direction at a constant speed are describing uniform motion.
