The Effect of a Falling Object's Weight On Its The Terminal Velocity
There are a number of factors that effect terminal velocity, such as
surface area, weight of object, height from which it is dropped, and
wind. I have chosen to investigate the weight of the object. It will
be the only variable that I change.
AIM:
The aim of this investigation is to find out what happens to the
terminal velocity when the mass and weight of the falling paper case
is changed.
PREDICTION:
I predict that the mass of the paper case will have a direct result on
the terminal velocity: the heavier the paper case, the faster the
terminal velocity will be. I am basing my prediction on the formula: (
). Also, if the paper case is heavier it will have more gravitational
pull pulling it down, thus increasing the speed. I also predict that
the lighter the paper case, the quicker it will reach its terminal
velocity. This is because to reach terminal velocity, the air
resistance has to be equal to the accelerating force, if the
accelerating force is less, then it should take less time for the air
resistance to become equal to it.
MY PRELIMINARY EXPERIMENT:
For my preliminary experiment, I did the experiment, but only using
the bare paper cases with no weights in, this was because I just
wanted to check if the height that we were dropping the cases from was
appropriate, and also to get used to using the apparatus. The
preliminary work that I did helped me to plan my actual investigation
better, as I learnt from the mistakes that I made. These were things
like starting the stopwatch slightly late or early, which changed the
times of my results. I also learnt that one metre was not high enough
as it did not give me enough time to start and stop the clock
accurately.
I am glad that I did a preliminary experiment, as now, when I do my
actual experiment I will feel more confident using the apparatus.
This conclusion was disproved from Milgram’s experiment. The majority of the subjects obeyed the experimenter to the end. There were several reactions to the experiment. Some people showed signs of tension or stress, others laughed, and some showed no signs of discomfort throughout the experiment. Subjects often felt satisfaction by obeying the experimenter.
In conclusion the experiment was carried out and had great success proving my prediction to be correct and enabling solid and valid results which were able to be put in a graph. I believe my prediction could have been more accurate or more backed up if I had made a quantitative prediction. Though what I believed would happen did happen during the experiment which helped to understand the graph and the results which led me to be able to write a thorough report on them.

Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
...s strength in the experiment rather than a limitation which future studies should also monitor.
In this inquiry the relationship between force and mass was studied. This inquiry presents a question: when mass is increased is the force required to move it at a constant velocity increased, and how large will the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground it is discovered that to drag a four-kilogram object is not four times harder than dragging a two-kilogram object. I hypothesize that increasing the mass will increase the force needed to move the mass at a constant rate, these increases will have a liner relationship.
There is not really that much I can do to help make this experiment a
An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force, expressed as the weight of the object. The weight equation which is weight (W) = mass (M) x gravitational acceleration (A) which is 9.8 meters per square second on the surface of the earth. The gravitational acceleration decreases with the square of the distance from the center of the earth. If the object were falling in a vacuum, this would be the only force acting on the object. But in the atmosphere, the motion of a falling object is opposed by the air resistance or drag. The drag equation tells us that drag is equal to a coefficient times one half the air density (R) times the velocity (V) squared times a reference area on which the drag coefficient is based.
As I do this experiment the thing I am going to be changing is the

Interestingly enough, one can actually change their "terminal" velocity. For instance, if Joe were to jump out of the plane and position in the prone, spread eagle position, his surface area would be at his maximum. Thus the terminal velocity he would reach would be lower than the terminal velocity he would reach if he dove from the plane head first. When Joe transitions from spread eagle to the head first position, his surface area decreases, thus allowing for an increase in speed.
First off, it should be stated that there are many different designs of paper airplanes and that different designs could affect the physics applied to it. If one paper airplane used a second set of wings or had a tail like a real airplane, those items would have more physics applied to them like extra drag.
The size of this depends on the mass of the object and the size of the
Does the momentum of an isolated system remain constant even after a collision and does the addition of mass on an object affect the momentum of an object?
