Lab Report Physics

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

The purpose of this lab is to test substances and to determine the physical and chemical properties of substances.

This soccer science fair project serves to acquaint students with basic information on how the amount of air in a soccer ball can affect the distance it travels when kicked with a consistent force. The greater the air pressure in the ball, the farther it will travel when a force is applied. In the process of conducting the research, the student will learn that atmospheric pressure may also affect how far the ball will travel. The student will learn about the relationship between air pressure and friction: the lower the friction, the farther the ball will go. The student will learn about concepts like air pressure, gravitational force, compression and expansion of air molecules, potential energy and kinetic energy. This science fair experiment

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason?

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,

-The more dissolved oxygen in the water, the more fish is observed in that area of water.

C. An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide.

6) Now click on ‘Circular’ on the bottom. Describe the motion of the ball and the behavior of the two vectors. Is there a force on the ball? How can you tell? Be detailed in your explanations.

The task that will be performed in the lab is a football snap toward a target. The subject will face way from the target, place their feet about shoulder length apart, place the ball between their feet, bend over and snap the ball through their legs to hit the target. For the experiment, the target is a wall. The wall is marked in increments of 20cm; a center space with five spaces above and below.

dependent variable- how far i will hit each ball due to what bat i use.

The subjects were given mimeographed answer forms that were assumed to match the ones in front of the test takers. The subjects answer forms contained the correct answers so that they could keep track of the test takers scores. There were two tasks consisting of twenty-five questions each. The first consisted of household objects and was female oriented. The second consisted of mechanical objects and was male oriented. There was only one task completed during each experimental session chosen by the experimenter. The instructions given to each subject emphasized that a person’s performance is influenced by factors such as luck, ability, and effort. These factors were told to be kept in mind as well as the tone and hesitation in the test takers voice.

Soccer is a sport that’s very challenging and during the course of this semester I’ve found physics can also be described as challenging. As far as I was concerned soccer and physics were both challenging and that was all they had in common, consequently upon researching them both this semester I found that I was wrong. For me this was nothing new because I’ve found that physics isn’t a subject that can be skimmed, but rather it has to be studied to the finest detail. Those small details if missed can make all your efforts worthless. Or on the positive side understanding those details can make your efforts worth it in the end. And in soccer if you understand the physics, which to most players

The accuracy of a person can be improved by playing video games that involves shooting and aiming at other objects. Shooting in a game is similar to shooting or throwing objects in real life. It takes predictions and precision. Not only in video games, but accuracy is a very important key factor in many sports as well. For example, soccer requires aiming the ball at a certain angle or direction to pass it to another player. (Frankl, 2000) This compares to the weapon shooting a bullet at a certain angle or direction in order to “snipe” another playing running or jumping. A group of participants helped with a study at the Ohio State University to test whether shooting games helped improve a player’s accuracy in real life shooting. In this experiment,

Data Each student had two attempts to get a full picture of the airplane’s capabilities. Figure 1 represents a comparative visual of the differing flight distances between participants and their two tests. The tests were done in a participant’s living room. Figure 1: Distance of each airplane trial launched by its builder.

There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.
