The question asks to identify the statement that is NOT true for an object experiencing non-uniform motion.
Understanding Non-Uniform Motion
Non-uniform motion occurs when an object's velocity changes over time. This change can be in speed, direction, or both.
Analyzing the Options
- Option 1: It moves unequal distances in unequal time intervals. This is characteristic of non-uniform motion, as the speed is not constant. Therefore, this statement is true for non-uniform motion.
- Option 2: Its velocity changes with time. This is the definition of non-uniform motion. Therefore, this statement is true.
- Option 3: The change in velocity is zero over time interval. If the change in velocity is zero, it means the velocity is constant. Constant velocity implies uniform motion, not non-uniform motion. Therefore, this statement is false for non-uniform motion.
- Option 4: It has different speeds at different points. A change in speed indicates a change in velocity, which is the hallmark of non-uniform motion. Therefore, this statement is true.
Conclusion on Non-Uniform Motion
The statement that is NOT true about an object in non-uniform motion is that the change in velocity is zero over a time interval. This condition describes uniform motion.
