Answer:
The motion in which every point on the moving body moves through the same distance in the same interval of time is called Translatory motion Translatory motion are of two types - Rectilinear motion and Curvilinear motion.
What is Translatory Motion?
☞ type of motion in which all parts of the body move the same distance in a given time is known as the translatory motion. Translatory motion can be of two types: rectilinear and curvilinear.
⇒If a body moves as a whole such that every part of the body moves through the same distance in a given time, then the body is said to be in translatory motion.
Translatory Motion Examples
Let us understand translational motion with the help of examples.
Let’s imagine a rectangular block placed on the slanting edge of a right-angled triangle. If the block is assumed to slide down this edge without any side movement, every point in the rectangular block experiences the same displacement, and more importantly, the distance between the points is also maintained. In pure translational motion, every point in the body experiences the same velocity be it at any instant of time. Both the points, P1 and P2 undergo the exact same motions.
A rectangular block sliding down the slanting edge of a right-angled triangle covers equal distance in equal intervals of time.
- A car moving in a straight line, the path of a bullet out of a gun, etc are examples of translational motion.
.
Rectilinear Motion
- When an object in translatory motion moves along a straight line, it is said to be in rectilinear motion
- A car moving along a straight path and the train moving in a straight track are examples of rectilinear motion
Curvilinear Motion
- When an object in translatory motion moves along a curved path, it is said to be in curvilinear motion
- A stone thrown up in the air at a certain angle and a car taking a turn are examples of curvilinear motion
