of a Ball Bearing Down a Ramp I intend to investigate what factors affect the acceleration of a ball bearing down a ramp. I will measure how long the ball bearing takes to roll down a ramp, and my other variable will be to measure the final velocity of the ball bearing rolling down the ramp. Using this information I will then be able to work out the acceleration of the ball bearing
Aim: How does the circumference of 5 different sized ball bearings affect the time it takes to reach the end of the V-ramp? Justify: The reasoning for looking at this experiment was when I was in the car going down a steep hill, and was wondering if the bigger the wheel of the car with the same mass if I would reach the bottom faster than if I had smaller wheels on the axel. Hypothesis: The larger the circumference of the bearings, the faster it would roll down the v-ramp as the force is pushing
distance between them, using the top of both tapes, to find my "fall distance" used in later calculations. I will then hold a sphere so that it is just touching the liquid whilst ready with a stop-clock to measure the time. I will then release the ball and begin timing when the sphere crosses the top of the start tape and stop the clock when is crosses the top of the end tape. I will repeat this for 5 different size spheres and repeat the experiment for each sphere 3 times and then
Mass of ball bearing · Viscosity/density of the fluid · Surface area of ball bearing · Texture of the balls surface · Temperature I am going to investigate how mass affects the terminal velocity. Prediction I think that as the mass of the ball bearing increases so does the weight of the ball bearing, which requires more friction to balance the ball bearing's weight thus making the terminal velocity increase. Mathematical Prediction I think that the mass of a ball bearing is directly
temperature of a fluid affects its viscosity. Method ------ Apparatus Required ------------------ * Water bath * Thermometer * Measuring cylinder * Steel ball bearing * Micrometer * Balance * Honey (100cm3) * Stopwatch * Ruler Plan ---- * Measure the radius of the ball bearing and also find its weight. * Find the mass of the honey. Weighing an empty measuring cylinder and then the same cylinder with the honey in it does this. The difference in the
v=velocity In the experiment the ball bearing will begin with potential energy. In order to predict the distance the ball travels I need to find out the horizontal speed of the ball upon leaving the rail. I will do this by making Ek equal to mgh to make a new formula, then making it equal to velocity. mgh = 1/2mv² gh = 1/2v² v² = ¶2gh v=¶19.6h h= height started v=velocity g=9.8 This formula will be used to find the horizontal speed of the ball which in the air will not change as
effects of an asteroid impact on Earth through a small-scale simulation. I shall be measuring the depth of the crater caused by a steel ball bearing being dropped from different heights into sand. I shall be dropping a steel ball into sand to simulate an asteroid collision, because the asteroid would be roughly spherical and have a high density, like the steel ball. The sand will react similarly to how the Earth would if impacted on. Planning An asteroid, also called minor planet, or planetoid
non-competition period; it was thus the first actual Ferrari car, but due to the war it saw little competition. In 1943 the Ferrari factory moved to Maranello, where it has remained ever since. The factory was bombed in 1944 due to making machines for ball bearing production, it was rebuilt in 1946 to include a works for road car production. The first Ferrari road car was the 1947 125 S, powered by a 1.5-litre V12 engine; Enzo reluctantly built and sold his automobiles to fund the Scuderia. While his beautiful
Smart Bombs: The History and Future of Strategic Bombardment Introduction Every kid loves to hear stories from their grandparents about something that they have experienced in their life. For me, some of the best stories came from my father about the air war that was waged over Europe during World War II. He often told me of a day that a formation of almost 1,000 bombers flew over his base: "The drone of the planes could be heard for miles and made us on the ground feel as small as ants
wood itself to see if it had been cracked or split. He then began talking to me about the trucks and their purpose; I studied and observed the hunks of metal. James then began to study the bearings and noticed that the bearings were extremely dirty. This was the cause of the noise. He told me that the bearings had to be clean. Too much friction was causing the noise. So James reached in his bag of tools, and got his mini monkey wrench and started to take off the nut that was holding the wheel to
Rolling-element bearings in electric motors support and locate the rotor, maintain a small and consistent air gap between the rotor and stator, and transfer loads from the shaft to the motor frame. The correct bearings for an application let a motor run efficiently across its design speed range, minimize friction and power loss, produce little noise, and have a long service life. On the other hand, bearings can be quickly ruined when a motor is used improperly. For example, the deep-groove ball bearings optimized
from Jane Austen’s famous novel, Emma, can be identified with their signs because of their unique personality traits. I believe the protagonist of the novel, Emma Woodhouse, is definitely a Leo. It is stated that “In grandeur of manner, splendor of bearing and magnanimity of personality, Leos are the monarch’s among humans”. This definition is clearly true for Emma for she bears the nobility in her manners and position. She has a great deal of self confidence, but she also has a great fear of being
brain is a very complex entity and we still don’t completely understand what happens when thoughts are processed. Scientists know that the brain is comprised of neurons that send signals to each other but the actual details are still not known. Bearing this in mind it is very hard to say whether or not something is thinking without a clear definition. The best I can do is to offer my own definition of thinking. I say thinking involves taking in information, making decisions, and being able to learn
ornamentals. While there are many useful plants in the family Euphorbiaceae, the sweet and bitter cassava plants (Manihot dulcis and Manihot esculenta), as well as the castor oil plant (Ricinus communis), are of greatest economic importance. Latex bearing plants are found in some 20 botanical families. The most prominent families include Sapotaceae, Moraceae, Compositae, Apocynaceae, Asclepiadaceae, and Euphorbiaceae. In total there are about 18,000 species of latex-producing plants. Yet, only a few
travelled. I will then drop the balls from my chosen heights. The sand = The moons surface. The balls =The meteors Variables: All the variables that I can change and what can affect my experiment are; * The height in which I drop the ball from. * The amount of sand in the tub. * The size of the different individual balls. * The weight of the balls. * Speed of which the balls are travelling at. * The surface type * The angle of which the ball hits the ground. All of
A Life Lived in Scouting 1986: Introduction to the Mystery After the skits, songs, and cheers, the Camp Director (bearing a white sash embroidered with a red arrow and two bars at each end) came forward. The crowd instantly grew quiet and somber. The wind rustled; the branches swayed and cracked; the lake gently lapped the shore. Sitting with my father, I watched bats flutter above two great fires. In a clear yet reverent tone, the weathered old man invoked the beauty of nature, the mystery of
story. Fourth, the hero recognizes his or her responsibility. Fifth, the story ends with a catastrophe. The catastrophe either may be an emotional event, this even may be a death. The Antigone is widely thought of as the tragic heroine of the play bearing her name. She would seem to fit the part in light of the fact that she dies doing what is right. Antigone buries her brother Polynices, but Creon does not like her doing that one bit. Creon says to Antigone, "Why did you try to bury your brother?
who trades his life as the prince of Jerusalem with the life of a slave. The story tells of his journeys and triumphs as a slave. The story starts with the five wise men as their journey to find Jesus. When they arrive in Bethlehem they come bearing gifts for the newborn king. After the birth of Jesus the movie changes to two Roman soldiers who are in a meeting. One of the soldiers, Tribune Musala, is an old friend of Judah. Judah comes in and meets with Musala and invites him to his home
plagued by excess water. This shows just one example of how trapping can be beneficial. Due to trappings benefits to the community, nature, and the individual trapper, it should be a welcomed outdoor activity. Trapping is the taking of wild fur bearing animals for the animal’s meat and the fur which is also called a pelt. These pelts are used to make clothing, shelters, and are sold for money. Trapping has a very long history going back to early anthropologic history and classic Native American
band of the Sioux. Black Elk's family was well known, and he counted the famed Crazy Horse as a friend and cousin. Black Elk's family was likewise acknowledged as a family of wise men, with both his father and grandfather themselves being holy men bearing the name Black Elk. The youngest Black Elk soon experienced a vision as a young boy, a vision of the wisdom inherent in the earth that would direct him toward his true calling of being a wichasha wakon or holy man like his predecessors. Black Elk's
