If we observe carefully,we will find that everything in the universe is in motion.However ,different objects move differently.Some objects move along a straight line,some move in a curved path,and some move in some other way.According to this we can say that there are three types of motion.Which are given as:
Translatory motion
Rotatory motion
Vibratory motionIn transnational motion,a body moves along a line without any rotation.The line may be straight or curved.”Watch how various objects are moving.Do they move along a straight line?Do they move along a circle?A car moving in a straight line has transnational motion.Similarly,an aeroplane moving straight is in transnational motion. Translatory motion is further divided into linear motion,circular motion and random motion.
Examples of translatory motion in daily life
Motion of train
motion of earth
motion of birds
motion of insects
motion of aeroplane
motion of gas molecules
Linear motion
“Straight line motion of a body is known as its linear motion.”linear motion
We come across many objects which are moving in a straight line.The motion of objects such as car moving on a straight and level road is linear motion. Aeroplanes flying straight in air and objects failing vertically down are also the examples of linear motion.
In the above diagram a boy is sliding in straight line which is the example of linear motion.
Linear motion examples in daily life
Motion of car on the road
Motion of football
Sliding a boy in straight line is the example of linear motion
Circular motion
“The motion of an object in a circular path is known as circular motion.”A toy train moving on a circular track.Earth revolving around the sun is the example of circular motion.
circular motion
A bicycle or a car moving along a circular track possesses circular motion.Motion of moon around earth is also example of circular motion.
Examples of circular motion in daily life
Motion of electron around the nucleus
Motion of toy car on circular track
Motion of planets around the sun
Random motion
“The disordered or irregular motion of a body is called random motion.”Have you noticed the type of motion of insects and birds?Their movements are irregular and disorder.Motion of insects and birds is random motion.The motion of dust or smoke particles in the air is also random motion.The Brownian motion of a gas or liquid molecules along a zig – zag is also an example of random motion.”Random motion of gas molecules is called Brownian motion.”
Rotatory motion
Rotatory motion definition
“The spinning motion of a body about its axis is called its rotatory motion.”
Study the motion of a tap.It is spinning about an axis.Particles of the spinning top move in circles and thus individual particles possess circular motion.Does the top possess circular motion?The top spins about its axis passing through it and thus it possess rotatory motion.An axis is a line around which a body rotates.In circular motion ,the point about which a body goes around ,is outside the body.In rotatory motion,the lone ,around which a body moves about,is passing through the body itself.rotational motion
Examples of rotatory motion in daily life
The motion of the earth about its geographic axis that causes day and night is rotatory motion.
The motion of wheel about its axis and that of steering wheel are the examples of rotatory motion.
Vibratory motion
“The motion of a body about its mean position is known as vibratory motion.”
vibratory motion
Consider a baby in a swing as shown in above figure.As it is pushed,the swing moves back and forth about its mean position.The motion of the baby repeats from one extreme to the other extreme with the swing.Motion of pendulum of a clock about its mean position,is also example of vibratory motion.Children playing in a sea saw is the example of vibratory motion.Besides these examples a baby in a cradle moving to and fro,to and fro motion of the hammer of a ringing electric bell and the motion of the string of a sitar are some of the examples of vibratory motion.Simple harmonic motion is also example of vibratory motion.
