Description: A ball is travelling with uniform translatory motion. This means that (a) it is at rest (b) the path can be a straight line or circular and the ball travels with uniform speed (c) all parts of the ball have the same velocity [magnitude and direction] and the velocity is constant (d) the centre of the ball moves with constant velocity and the ball spins about its centre unifomly

Key Concepts

Uniform Motion

Uniform motion means moving with constant speed and direction, implying that there is no acceleration. When combined with translatory motion, it indicates that not only does every point of the body move with the same velocity, but that velocity remains constant over time.

Rigid Body Dynamics

In rigid body dynamics, objects are considered to be non-deformable, so their motion can be analyzed by considering both translation and potential rotation. For uniform translatory motion, the entire rigid body moves without any internal relative motion between its parts, meaning every point, including the center of mass, follows the same trajectory with constant velocity.

Translatory Motion

This type of motion occurs when every point in a body moves in parallel paths; that is, all points of the body have the same velocity in both magnitude and direction at any given time. In pure translatory motion, the orientation of the body does not change with respect to its path.
