define translatory motion. explain its types also....
plz answer full question...not half..
explain it's types also....

The motion in which all the particles of a body move through the same distance in the same time is called translatory motion. The examples of translatory motion are – a car moving along a road, a ball rolling on the ground, pulling out a drawer, firing of a bullet from a gun, a stone hurled from a catapult etc.
- Rectilinear motion: If a body moves in a straight line then it is called rectilinear motion.
- curvilinear motion: If a body moves along a curved path is called curvilinear motion.

What is translatory motion?
Translational motion is the motion of body where body moves in the linear path. It is the motion in which all points of a moving body move uniformly in the same line or direction.
The bullet gets fired from the gun undergoes rectilinear path. Here all the points of the body which is in motion are in same direction. Translational motion is generally seen in rectilinear motion when body moves in a straight line. It does not mean the earth revolving round the sun is complete rotational motion as the rotation might a rotational motion but the revolution is a translational motion. If the body covers the distance x in time t the translational motion would be the function of t.
According to E.T. Whittaker “If a body is moved from one position to another, and if the lines joining the initial and final points of each of the points of the body are a set of parallel straight lines of length ℓ, so that the orientation of the body in space is unaltered, the displacement is called a translation parallel to the direction of the lines, through a distance ℓ.”
There are two types of translation motion; rectilinear motion and curvilinear motion.
