## EXPERIMENT 2: FREE FALL

One of the major topics discussed in Physics is the study of free fall, or the effect of the force of gravity on any object. This experiments aimed to investigate the mechanics or the action of gravity an object by analyzing certain vectors related to free fall versus time graphs. These studies on free fall are important if further studies of projectile motion are being made.

The objective of the study is to show that velocity, acceleration and distance are related such that one is actually the slope of the other. The slope of velocity is acceleration. The slope of distance is velocity. Hence, changes in one of the factors involving a certain object, the other related factors are also inevitably altered. This exercise also seeks to prove the constant of acceleration due to gravity.

The first activity utilized the ULI, photogate and Logger Pro systems to analyze graphs for free fall.

Middle

The average slope of the graph of velocity vs. time in five trials was taken to compare with the theoretical acceleration of gravity (9.8m/s2).

Conclusion

However, the orientation of the graph may be changed. Remember that before jumping, the indicator arrow was flipped upwards. The effect on the graph was it shot downwards at peaks of the jump, and it moved upwards whenever the representative landed. If the indicator arrow is flipped downward, the previous graph will also be flipped. Instead of an increasing positive value as one descends, the meter will read an increasingly negative value. This is simply an indication of the direction of the acceleration., which going down.

In this activity, we have learned the relationships between time, distance, velocity and acceleration. In addition, we are also able to confirm the presence of acceleration due to gravity. Even if the theoretical is 9.8m/s2 , the presence of factors like air resistance lessens this value.

This student written piece of work is one of many that can be found in our GCSE Forces and Motion section.
