Therefore, objects of either same or different masses will reach the ground at the same time. However, there are several factors that can impact this occurrence, including air resistance.

Balls with a larger diameter fell more slowly due to a small amount of air resistance that was created during the free fall.Īll objects fall to the ground at the same acceleration, 9.8 m/s/s.

It is important to consider that despite the size of the ball, it fell at an acceleration of 9.8 m/s/s due to the effects of gravity. Construct a velocity-time graph, draw a best-fit line, and calculate the slope to find the acceleration in cm/s 2 and m/s 2 Position (cm) Time (s) 0 0.05 0.10 0.15 0.20 0.25 0.30 0.35 0.40 0.45 0.50 0. The larger the diameter of the ball, the longer it would take for the ball to fall, while the ball with the smallest diameter fell the quickest. Ultimately, the ball with a greater diameter contributed to a greater degree of friction, which slowed it down compared to the balls with a smaller diameter. The results demonstrate that while the mass of the ball does not impact the amount of time it takes for the ball to reach the ground, the diameter of the ball has a small impact on this process. Results were collected in an Excel file for further analysis.
Acceleration due to gravity lab answers falling object trial#
Each trial was conducted at least three times. Each ball was dropped from a height of five feet and the amount of time it took to reach the floor was measured using a stopwatch. The weight and diameter of each ball used in the experiment was recorded. I hypothesize that each test ball will reach the ground at the same time because the acceleration due to gravity will act on the objects equally. The purpose of this experiment is to determine the amount of time that it will take for balls of different sizes to reach the ground when they are released from the same height. Despite this, mass is not expected to contribute to the overall acceleration of the object because the acceleration due to gravity will act on the objects equally. Therefore, large, flat objects are likely to exhibit the greatest extent of air resistance while dense, compact objects are less likely to experience this effect. While all objects are known to accelerate downwards at 9.8 m/s/s, the shape of the object has the ability to impact the average velocity of the fall due to the effect of air resistance. Considering pendulums, their practical value is apparent since they are used as parts of clocks, metronomes, and seismometers.Objects free fall due to the influence of gravity. For example, the power of gravity allows artificial satellites to orbit around Earth without falling as their mass is calculated regarding acceleration due to gravity. The equation of motion for any body starting from rest and undergoing constant acceleration (in our free fall coordinates) is given by: where x is the distance. If materials of different weights, size, or shape had been used in the performed lab exercise, the results would still be the same because the physical force of gravity is constant for all falling objects.Īnother significant aspect of this lab exercise is that it was not merely an academic exercise because the concept of acceleration due to gravity is highly applicable in practice. As acceleration due to gravity is the physical constant, it does not matter what shape and size are the falling objects (any other thing could be used instead of the paper strip), and thus both methods give the same result, despite that the input data differs. It is also highly important to emphasize why the same quantity derived from two different activities.
