Types of Motions:
1. When we discuss about motion, it is important to be aware that there exist different types of motions and each type is dependent on a particular situation.
2. Let us consider the following examples.
3. A car travelling along a straight road.
4. Motion of blades of a ceiling fan.
5. Motion of needle in a running sewing machine.
6. Motion of pendulum in an old wall clock.
7. Considering the direction of motion what differences do we notice in above examples?
8. The motions in the above examples are different in terms of direction of motion.
a) Car is moving in same direction along a straight line.
b) Blades of ceiling fan rotate about a fixed line in a circular path.
c) Needle of sewing machine moves up and down about a fixed point.
d) Pendulum of the wall clock oscillates ‘to’ and ‘fro’ about a fixed point.
9. Based on the path taken by the bodies in motion we classify motion of bodies as,
1) Translatory motion
2) Rotatory motion
3) Oscillatory motion
