Free Fall

The purpose of this experiment is to see how height affects distance and to see how adding additional height affects the distance that the ball travels. Also, to see how gravity pulls the ball down storing energy and releasing the energy as the ball hits the bottom of the ramp and to see the distance the ball travels after books are added.

There were many opportunities for error within this lab due to the procedure the group decided to follow. However, the percentage error was not very significant, with a 1.12% to 6.71% difference between the actual and predicted velocity. The slight difference between the percentages could have been a result of parallax, instrument resolution, environmental factors, and the lack of trials. Once major source of error was the group’s decision to bypass collecting many data trials in the interest in time. This may have introduced biased sample fallacy into the conclusion because there were only two trials per a flying toy and which was little evidence to support the statements made about the relationship between velocity, acceleration, and circular motion. For the next lab, the group plans to conduct at least three trails and then use the average to avoid this bias. Environmental errors present during this lab included classmates walking into the flying toy while the group was collecting data,

There are many connections between Jason Helmandollar's "The Backward Fall" and "Falling" by Elizabeth Baines. "The Backward Fall" describes a woman who suffers from Dementia, and how her husband takes care of her. A woman in "Falling" dreams about her falling for the first time, thinking she was in a coma. After, she falls for a second time, believing she had died. Many unique connections can be created between the stories.

From the first test, which had the dummies sitting upright, and the data was: 41ft/sec, 54 milisec collision time, and 21g-force exerted on the

Evaluation: I think that this experiment was a great experience for me, as I have a chance to discover the real physics behind our everyday lives, in my case, how the steepness of the hill can affect the velocity of a

Surviving a plunge surrounded by a semiprotective cocoon of debris is more common than surviving a pure free-fall, according to Hamilton's statistics; 31 such confirmed or "plausible" incidents have occurred since the 1940s. Free-fallers constitute a much more exclusive club, with just 13 confirmed or plausible incidents, including perennial Ripley's Believe It or Not superstar Alan Magee—blown from his B-17 on a 1943 mission over France. The New Jersey airman, more recently the subject of a MythBusters episode, fell 20,000 feet and crashed into a train station; he was subsequently captured by German troops, who were astonished at his survival.

I thought it would be fun to fling things like raw eggs and rocks with a catapult. Guess

With the threat of zombies quickly approaching, a spring catapult needed to be built to protect Rome High School and the rest of the world from the upcoming apocalypse. That catapult is the Medieval Catapult Lier (aka MCL) which can be analyzed from the picture at the bottom of this essay. The MCL went through many adjustments such as in arm length, nail strength and tension before it could launch a tennis ball at a significant distance. Nevertheless, it was all worth it and could not have been done without the crucial subject of physics and the study of motion and energy.

to the measured data. Doing so may allow for further understanding concerning the possible errors

The purpose of the experiment was used to determine which team created a design that ultimately proved to launch the marshmallow the farthest. What was determined to be true was that the structure that contained the right configuration in producing a high amount of force proved to have the greater amount of displacement of the marshmallow. This proved the group’s hypothesis. However, when the group was compared to other groups conducting the same experiment, the displacement of their marshmallow was the shortest. This was a result of miscommunication between group members that proceed to affect why the group had the lowest measurement of displacement. As mentioned in the research, projectile motion was shown when the marshmallow was launching

The purpose of the lab is to find a projectile’s horizontal velocity and make comparisons of the effects of different inclined planes with the projectile of a ball.

In this lab we tested the effect of the air friction on a free fall object using a stopwatch and photogate. One of the objective of the experiment was to get one of the free falling object acceleration to be close to 9.8 meter/second sq. The reason of that objective was to see if the theory of the acceleration of any object in free fall is downward on earth have the magnitude of about 9.8 meter/second sq. or not. To accomplish this we separated this experiment in two part.

The goal of the experiment was to identify the gravitational acceleration from the recorded distance(cm) vs time(sec) data of a fallen object. The first step was to graph the distance-time graph from the data collected. Upon graphing the data, the best fit line was identified in order to find the formula of the function. As the data is representative of a graphical parabola, a parabolic function was utilized to be the best fit trendline. The function Positon=404.289cm/s^2(t^s) + 44.450cm/s(t) +4.876cm was identified. In the equation, 404.289cm/s^2(t) represents the slope of the parabolic curve pertaining to the distance(cm) over time(sec) as the 4.876cm displays the y-intercept in which the function crosses the axis leading to the resulting curve. From identifying the distance-time graph equation, the next step is to find the velocity of the set data.

The reason of these really close dots are because of the impediment of the decline of the weight. If the interval between each dot is very small it might cause the measurement of inaccurate results, therefore skewing the

Projectile 2 Lab Report Kelsy Ecclesiastre and Sara Lopez AP Physics 1 Period 6 Objective/Purpose: To correctly identify the range of a projectile when fired above the horizontal axis with only a meter stick (i.e. no timer). Background: According to Henderson, speed is how far an object travels during a specific amount of time and does not include the direction.
