What does non-uniform velocity indicate about an object's motion?

• A. The object maintains a constant speed in a straight line.
• B. The object covers equal distances in equal intervals of time.
• C. The object changes speed or direction in equal intervals of time.
• D. The object moves at a fluctuating speed.

Answer: (C)

Non-uniform velocity indicates that an object is experiencing changes in either its speed or direction, or both, as it moves. This means that over equal intervals of time, the object does not maintain a constant speed or trajectory. Instead, it may be accelerating or decelerating, or it could be changing its direction while maintaining a particular speed. In the context of the choices provided, non-uniform velocity encapsulates scenarios in which the object's motion is not uniform, which means that the motion is variable. The correct understanding of this concept is crucial for analyzing situations in mechanics where forces and motion are involved, especially when studying concepts like acceleration and resultant forces. In comparison to the other options: - The notion of maintaining a constant speed in a straight line refers to uniform velocity. - Covering equal distances in equal time intervals also describes uniform motion, which contradicts the idea of non-uniformity. - Fluctuating speed would suggest variability, but it does not explicitly incorporate changes in direction, which is a key element of non-uniform velocity. Thus, the most comprehensive definition is that non-uniform velocity involves changes in speed or direction over equal intervals of time.
