to the equation one must use precisely 2, not 1.99 or 2.001. The force of gravity has been tested over and over with sensitive torsion balances and has shown repeatedly that the factor must be precisely two up to five decimal places. Similar to the mass of a proton which cannot be changed without catastrophic results, if any value other than 2 is substituted in the equation, it would result in the eventual decay of orbits and the disintegration of the whole universe. This precision found within…

When a ball is kicked at its side it begins to spin around in its place according to the location of the kick. If it is kicked at the side and a bit towards the bottom the ball rises up in the air while spinning on its own axis. In the beginning it will fly exactly in the direction of the kick, and as it slows down due to friction with the air, the spinning motion will cause the air on one side to move faster than that on the other side and because of the Magnus effect the ball will then change…

Why am I doing this lab? In this lab we are determining which of the two scientists Aristotle or Galileo has the correct theory in the laws of a falling objects. Aristotle was a physicist who was born in 384 BC and his theory is that when a object falls it keeps a constant velocity. Galileo was also a physicist but born years later in 1564 and his theory is that when an object falls it changes velocity. At the end of this lab we will figure out who's theory is correct. Hypothesis My…

The History A Requiem is sung at a funeral mass to give the soul entry to heaven. They were mostly personalized because mostly wealthy people would hire someone to create a Requiem when they were dying. John Rutter John Rutter was born in London in 1945. He first studied music as a chorister at Highgate School. He finished his education at Clare College, Cambridge. There he wrote and published his first compositions. He also conducted his first recording while still a student. Some of his…

My Ted-Talk I am 5’8”, weigh 130 pounds, and have a BMI of 19.5, the healthy range being from 18.5 to 24.0. My freshman year I was 5’8”, 140 pounds, and had a BMI of 21.3, still within the healthy range. In reality these numbers really tell you nothing about my health practices now, and my health practices then. My health practices today include clean-eating, vegetarianism, running cross country, and frequent gym visits. Just knowing my weight however, does not reveal any of this. I have enough…

Introduction In this lab, we are measuring the ranges R of the ball as the function of the heights, H, that the ball is dropped from. I will use these data to determined the relationship between the height and the range. Procedure We divided this experiment into three parts. In the part one, the object was to observe the scatter in data. To do this, we set up the equipment: the bounce plate is 20 cm above the table ,the drop plate 20 cm above the bounce plate, a piece of carbon paper…

Specify the sources (causes) of friction. The causes of friction in this lab come from three different sources. One is the string sliding over the pulley wheel. Another is the pulley wheel turning on its axle. Also, the string sliding through the hole; all these cause friction in our experiment. Glider on Frictionless Air Track Lab The acceleration of the glider can be calculated by tracking the speed as it passes through the two photogates. On the frictionless air track a glider is placed on…

boiling, measure the mass of your metal object, marking off your answer to one more decimal place than what the scale marks off. Once the water is boiling, drop the metal into the water, leaving it in for about five minutes to allow it to reach the temperature of the water (100.0 °C) Place one Styrofoam cup into the other. This will be your calorimeter. Measure the mass of the calorimeter. Fill about ¾ full with room temperature water, then measure the mass again, determining the mass of the…

the circumference of a soccer ball. The typical radius of a soccer ball is 8.65 inches and the diameter of a typical is 17.3 inches. All of these measurements are important to find the weight of the soccer ball, and the ball’s mass. The equation to find mass is Density=Mass/Volume, to find volume for a sphere the equation is Volume=4/3πr^3. The average weight of a correctly-inflated soccer ball is 420-450 grams, or 0.925942 0.99208 pounds. The weight of the ball is important because it can…

Chapter 4 Questions 1. If the acceleration of an object is zero, are no forces acting on it? Explain. a. No, forces would still be acting on an object if its acceleration is zero. Acceleration is only the change in velocity and in the F=ma equation, the F stands for net force. For example, if a car was traveling at a constant velocity, it would still have forces such as gravity, friction, and normal force acting on it. 2. Only one force acts on an object. Can the object have zero acceleration?…
