The motion of a ceiling fan's blades is a/an _____________________. 

Uniform motion is defined as the movement of an item along a straight path at a constant speed. This signifies that the body's velocity remains constant while it travels equal distances in equal time intervals. 

In the event of uniform rectilinear motion, the body's acceleration is zero. In this case, the object's average speed equals its actual speed. 

An automobile traveling at a consistent pace, a child sprinting in a straight line at a constant speed, and so on are examples of uniform motion.

In the similar manner, the motion of a ceiling fan's blades also reflects uniform motion.
