Yes, moving a clock's minute hand is a rigid motion because the shape and size of the hand do not change during the movement. The hand rotates around a fixed point (the clock center) without any distortion.
Pendulum clocks are made of metals because metal is a durable and stable material that can withstand the forces and movements associated with the swinging motion of the pendulum. Metals are also rigid and resistant to corrosion, factors that contribute to the accuracy and longevity of the clock's mechanism.
A rigid motion transformation is one that preserves distances and angles between points in a geometric shape. Anything that involves changing the size or shape of the object, such as scaling or shearing, would not describe a rigid motion transformation.
A translation is a type of rigid motion, which means it preserves distances and angles between points. In a translation, every point in a figure moves the same distance and direction. Rigid motions also include rotations and reflections.
Dilation, shear, and rotation are not rigid motion transformations. Dilation involves changing the size of an object, shear involves stretching or skewing it, and rotation involves rotating it around a fixed point. Unlike rigid motions, these transformations may alter the shape or orientation of an object.
A rigid link is a structural component that connects two parts of a mechanism or machine in such a way that the relative position between the two parts remains fixed. It does not allow for any movement or flexibility between the connected parts. Rigid links are commonly used in engineering and design to provide stability and precise motion control.
Movement of a shape can involve flexing - for example, a square frame being flexed into a rhombus. Rigid motion excludes such motion: the shape of the moving object does not change.

Translation is considered a rigid motion because it involves moving every point of a shape or object the same distance in a specified direction, preserving its size and shape. During translation, there is no rotation or distortion; the relative distances and angles between points remain constant. This characteristic ensures that the object retains its original form and orientation throughout the motion.

The key difference between a particle and a rigid body is that a particle can undergo only translational motion whereas a rigid body can undergo both translational and rotational motion
