The object covers unequal distances in equal intervals of time, it is said to be in _____ motion.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3: Non-uniform.
Explanation:
- When an object covers unequal distances in equal intervals of time, this motion is termed Non-uniform motion.
- Example: A car moving on a crowded road, or a person jogging. Here, the speed does not remain constant; rather, it changes over time.
- Acceleration: In non-uniform motion, the velocity of the object changes; therefore, there is always some degree of acceleration involved.
Analysis of Other Options (Quick Revision):
- Uniform (Option 1): When an object covers exactly equal distances in equal intervals of time (e.g., the Earth rotating on its axis). In this case, the speed remains constant.
- Linear (Option 2): When an object moves along a straight line. This motion can be either uniform or non-uniform.
- Circular (Option 4): When an object moves along a circular path.

Question: What type of motion is exemplified by a freely falling object (Free fall)?
Answer: Non-uniform motion (because its velocity continuously increases due to gravity).
Question: What is the shape of the 'Distance-Time Graph' for uniform motion?
Answer: A straight slanting line.
Question: What is the formula for calculating Average Speed?
Answer: Average Speed = Total distance covered / Total time taken
