The basic difference between constant velocity and uniform velocity lies in their definitions and implications:
Constant Velocity: Constant velocity refers to the motion of an object when its speed and direction remain unchanged over time. In other words, an object moving with constant velocity covers equal distances in equal time intervals, and its motion follows a straight line path. This means there is no acceleration acting on the object. Constant velocity implies a steady, unchanging movement without any changes in speed or direction.
Uniform Velocity: Uniform velocity also denotes the motion of an object with a constant speed. However, uniform velocity allows for changes in direction as long as the speed remains constant. In uniform velocity, the object covers equal distances in equal time intervals, but the path it takes may not necessarily be a straight line. It can move along a curved path or change direction as long as the speed remains the same. Like constant velocity, uniform velocity also implies the absence of acceleration.
In summary, the key difference between constant velocity and uniform velocity is that constant velocity refers to a motion with an unchanging speed and direction along a straight line, while uniform velocity refers to a motion with a constant speed but allows for changes in direction, including curved paths.
