Investigating the Bounce of a Tennis Ball after It Has Been Dropped From Certain Height Aim To investigate how high a tennis ball will bounce back after it has been dropped from a certain height How a Tennis Ball Bounces As the ball is elevated the ball gains gravitational potential energy equal to the ball's weight multiplied by its change in height1. When the ball is dropped, the height decreases, and therefore so does the gravitational potential energy. At the same time, the velocity
vary two factors in this experiment to determine their affect on terminal velocity; these will be the drop height and weight. I will record the time taken for a cake case, or a stack of cake cases, to fall from a certain height and record the results. To make sure that I am only recording the time when the object has achieved terminal velocity I will drop the object from 20cm above the height and start timing when it comes past that point. Diagram: Factors that affect terminal velocity:
Forms of capital punishment that are still used in the United States include hanging, firing squad, electrocution, gas chamber, and lethal injection. With hangings a rope is attached to a persons neck proceeded with them being dropped from a certain height with the other end of the rope attached to something higher than them. The result is either strangulation which can take a while or complete decapitation. With the firing squad option a prisoner is tied to a chair and blinded. After this a firing
arched feet, long, elegant legs and a graceful extension (Solway 57). He believed that the thinner the dancer, the better one could see their bodies and movements. Due to the views of George Balanchine, it soon became the norm for a dancer to be a certain height and weight. Soon that is what company producers, directors, choreographers, and the public expected. Even today, “an ideal has been set in place in the dance community which reflects the general public’s desire to see thin women on stage” (10-6)
They had to be literate and be able to do basic subjects such as maths. They had to have certain height and chest measurements comparing to their age. I.e. if you wanted to join the Royal Marines Artillery: Age Height Chest 17-18 5ft 7.5 35 18-19 5ft 8 35.5 19-20 5ft 8.5 36 20+ 5ft 9 36.5 If you wanted to join the Royal Marines Infantry: Age Height Chest 17-18 5ft 5 34 18-19 5ft 5.5 34.5 19-20 5ft 6 35 20+
Investigating How the Height From Which a Table Tennis Ball is Dropped Affects Its Bounce When a table tennis ball is dropped onto a surface it bounces. The height of the bounce depends upon a number of factors; the pressure of the air in the ball, the height from which it is dropped, its material, mass and its temperature; the type of floor surface, its temperature and its angle; and the acceleration due to gravity, the temperature and the air resistance of the air that the ball will pass
Also to find out which wing length would produce longest flight time. Method: Firstly, I made a whirlybird model and timed how long it took to reach the floor from a certain height. This procedure was repeated several times, each time lessening the wing length and keeping the same height. For each wing length, the bird was dropped three times for maximum accuracy. Once this data was collected it was transferred into a graph, and strange points were excluded. After
In Emily Dickinson’s lyrical poem “There’s a certain slant of light” she describes a revelation that is experienced on cold “winter afternoons.” Further she goes to say that this revelation of self “oppresses, like the Heft of Cathedral Tunes” and causes “Heavenly Hurt”, yet does not scare for it is neither exterior nor permanent. This only leaves it to be an internal feeling, and according to Dickinson that is where all the “Meanings” lie. There’s no way for this feeling to be explained, all that
Investigating the Effect of Temperature on the Height a Squash Ball Bounce Aim: To investigate the effect of temperature on the height a squash ball bounces. Prediction: I think that the higher the temperature of the squash ball, the higher the squash ball will bounce. I think that as the temperature doubles so will the height of the bounce. I think that they will be directly proportional. Scientific Knowledge: If you drop a ball onto a hard floor. It will rebound, but even the bounciest
could reduces their precision and influence on their accuracy. (Sicotte et al, 2010; WHO, 2000) 1.4 Aim of the study The aim of this study report was to interpret and appraise information related to nutritional status from measures including height, weight, waist circumference, ulna length and mid-upper-arm circumference (MUAC) assessed during a
Investigating the Minimum Release Height Needed to Loop the Loop Task What is the minimum release height needed to “loop the loop.” Investigate and validate. To do this I will create a theoretical model to calculate the minimum height required for the roller coaster to just reach the top of the loop then look at the height required to fully complete a loop. I will validate my theoretical model using a track. Assumptions So I can make a relatively simple model I will have to
different grids and record the peaks to try and establish a pattern. My initial grid size will be 12cm x 12cm and I will increase this as I continue my investigation. The volume will be calculated by multiplying the length by the width by the height. When I appear to reach a maximum volume I will try cut sizes 0.1cm smaller and larger than the cut size that appears to give the maximum volume. If the volume increases then I will make the cut size smaller or larger by 0.1cm again. I will repeat
A=1 and N= a positive integer. Y=X2 X Height Width Gradient 1 1 0.5 2 2 4 1 4 3 9 1.5 6 4 16 2 8 Looking at the results above I can see that the gradient is twice the X value, the height is X2 and the width is 1/2 the X value. This shows me that there are several patterns in the graph but there is not enough to make a formula on so I am going to do another graph Y=X3 X Height Width Gradient 1 1 0.33 3
Investigating the Relationship Between Foot Size and Height I predict that the taller the pupil is, the bigger their foot size will be. Plan ==== I’ve been given 60 pieces of data from pupils, about their height and foot size. I will be using a piece of software called Fathom where I will place this information into a scatter graph, to see whether or not my hypothesis is correct. Fathom will produce a line of best fit on my graph and tell me what my r-value is. The r-value shows
The Change in Resistance of a Carbon Paper Introduction The aim of this experiment is to see how the resistance of a carbon-coated piece of paper changes when the different variables change. Variables A variable is a change in an experiment that could alter the outcome/results of that experiment, and for this experiment the main variables are type of paper, width of paper, length of paper, and temperature. We are going to be studying how changing the width of the paper affects
Analysis of Data Between Height and Weight in Girls and Boys In my first investigation, I will be analysing data between height and weight in girls and boys. I will also use this data to compare the results between boys and girls as well. I will use a variety of graphs to show this. PREDICTIONS I predict that as the heights increase, so will the
Investigating How the Size of a Shadow Depends on the Angle at Which the Light Hits the Object Introduction ============ The aim of the project is to see which factors affect the size of a shadow and then to look more closely at one of the factors to see how exactly it varies the size of a shadow. Variables that may affect the size of the shadow ================================================ Although, I will investigate how one factor affects the size of a shadow, there
The Relationship Between the Length of Constantan Wires in a Circuit and the Current Aim To investigate the relationship between the length of constantan wires in a circuit and the current flowing through. Introduction ============ In a conductor electrons are able to jump between atoms. However in insulators they remain around a single atom unable to move. Constantan, a metal, unlike most other metals is a poor conductor although it is also a poor insulator. Being a metal it
Factors Affecting the Resistance of a Metal Wire 1. Investigate some of the factors that affect the resistance of a metal wire. The current and voltage will be measured and then V = IR will be used to calculate the resistance. The potential divider circuit produced better results in the investigation into how resistance depends on the number of identical resistors connected in series, so this circuit will be used for this investigation, too. Variables and Constants 2. Possible
me. Since the concept of inequality is existent, I decided to try to find where it was located in Jersey City. Jersey City is divided into several sections: Heights, Downtown, Journal Square, McGinley Square, Westside, Bergen/ Lafayette, and Greenville. The major races in these areas also differ greatly throughout. Starting with the Heights and Downtown, the white population is highest. Journal Square has many Indians while McGinley Square holds mostly Middle
