Question

Define rigid body translatory motion and rotatory motion ​

Answer 1

Hey mate ☺

☺ ANSWER ☺

Describe briefly translatory and rotatory motion of a rigid body. ... Rotational Motion: In rotatory motion of a rigid body about a fixed axis, every particle of the body moves in a circular path lying in a plane perpendicular to the axis and has its centre on the axis.

I hope Answer helpful ❤ ☺
Happy deddy day

Answer 2

Answer

⚫Rigid body

◾A Rigid body is that whose shape and size does not vary under the motion.

⚫Translatory motion

◾If all the particles of the body have the same velocity at any instant then such a motion is called Translatory motion

⚫Rotatory motion

◾If every particle of the body moves in a circle which lies in a plane perpendicular to the axis of rotation and if the line of points remain fixed then such a motion of bodies is known as Rotatory motion.
