The question asks to identify the term defined as the ratio of the total path length travelled by an object to the total time interval of the motion.
Average Speed Definition Explained
Average speed is defined as the total path length (or total distance covered) by an object divided by the total time taken for the travel. It is a scalar quantity, meaning it only has magnitude and no direction.
The formula is represented as:
\( \text{Average Speed} = \frac{\text{Total Path Length}}{\text{Total Time Interval}} \)
Why Other Options Are Incorrect
- Instantaneous velocity: This is the rate of change of an object's displacement at a specific moment in time and includes direction. It is not based on total path length.
- Instantaneous acceleration: This is the rate of change of velocity at a specific instant. It is unrelated to the definition provided.
- Uniform acceleration: This means the acceleration is constant over time. It does not directly relate to the definition based on total path length and total time.
Therefore, the correct term matching the definition is Average speed.
