The time it takes for a ball to drop from four different heights is recorded in the data table. Which of the following graphs best represents the data?
Graph B (Time on y-axis, Height on x-axis, curve increasing less rapidly, more parabolic)
The relationship between the height from which a ball is dropped and the time it takes to reach the ground is governed by the principles of free fall under the influence of gravity, which results in a parabolic graph when height is plotted against time. As the height increases, the time taken to fall increases at a decreasing rate, creating a curve that reflects this non-linear relationship.
This graph suggests a rapid increase in time with height, which does not accurately represent the physics of free fall. In reality, the time increases but does so at a decreasing rate, indicating a parabolic rather than exponential relationship.
This graph correctly illustrates the relationship between height and time in free fall, where time increases as a function of the square root of height. The parabolic shape of the graph is consistent with the equations of motion under gravity, making it the best representation of the data.
This graph implies a linear relationship between height and time, which is incorrect. The time taken to fall does not increase linearly with height; rather, it increases in a parabolic manner, as dictated by the laws of motion.
Similar to Graph A, this graph suggests a rapid increase in height with time, which is not supported by the physics of free fall. This incorrect representation does not align with the expected parabolic relationship between the two variables.
The correct representation of the relationship between the height from which a ball is dropped and the time it takes for it to reach the ground is reflected in Graph B. The parabolic curve effectively demonstrates that as height increases, the time taken to fall increases at a decreasing rate, aligning with the physics of free fall. The other graphs fail to accurately depict this non-linear relationship, reinforcing the importance of understanding the underlying principles of motion.
