Uniform linear motion is motion that occurs in one dimension of space at a constant speed and direction. It is a key principle of physics, directly related to Newton's first law.
Uniform linear motion occurs when an object with no net force pushing against it either stays still or moves in a straight line at an unchanging speed. When the item is in motion it creates kinetic energy from the momentum of the movement.
An example of uniform linear motion is a group of people marching together in a parade, performing the exact same steps together. In contrast, an example of non uniform linear motion is a child going down a slide, as they are constantly changing speed and position.
