When the velocity of a body decreases uniformly to zero, it means that the body is coming to a complete stop. In this scenario, we cannot call the body's velocity uniform as uniform velocity means that the body is moving at a constant speed in a straight line. However, when the body comes to a stop, it is no longer moving at a constant speed, and therefore, it cannot have uniform velocity.



Uniform velocity is a term used in physics to describe the motion of an object that is moving at a constant speed in a straight line. When an object has uniform velocity, it means that its speed is not changing, and it is moving in a straight line. For example, a car moving at a constant speed of 60 mph on a straight road has uniform velocity.



When a body is moving in a straight line, and its velocity decreases, we call it deceleration. Deceleration is the opposite of acceleration and is often referred to as negative acceleration. Deceleration occurs when an object is slowing down, and its speed is decreasing.



In conclusion, when the velocity of a body decreases uniformly to zero, it means that the body is coming to a complete stop. It cannot have uniform velocity as uniform velocity means that the body is moving at a constant speed in a straight line. Therefore, we can say that the body has undergone deceleration.
