In pure translational motion every particle of the body moves with same velocity at any instant of time.
All the particles of the rigid body have same displacement, velocity and acceleration.
Pure translational motion is of two types,
- Rectilinear translational motion
- Curvilinear translational motion
2.1.1 Rectilinear translational motion
In rectilinear translational motion, all points in a body moves on a parallel straight line path.
2.1.2 Curvilinear translational motion
In curvilinear translational motion, all points in a body moves on a congruent curve.
