Why Objects Fall In Fluid's Viscosity
After the experimentation, you may ask yourself “Why did all of these spheres fall at a different rate when Galileo said that objects fall at the same rate (in a vacuum)?” The reason why the objects fell at a different rate in the fluids given was because the fluid’s viscosity varies. The viscosity of a fluid can impact an object that you drop into it, because there’s a resistance of some sort impacting the rate of which they fall. For example, when both spheres were dropped at the same time into a graduated cylinder of water, the steel sphere hit the bottom of the graduated cylinder before the glass sphere, because the viscosity of water is low. The viscosity of water is very dynamic based on the temperature, but both of the spheres were denser
Chapter 5 Summary Of Buoyancy
267 Words | 2 PagesIn chapter five, Pink discusses the trait of “buoyancy,” or what he defines as the ability to stay afloat when waves of rejection and adversity strike. According to Pink, buoyancy is composed of three different components: interrogative self-talk, positivity ratios, and explanatory self-talk. In the first component, Pink suggests that instead of only using positive self-talk whenever we are planning to move someone, we use interrogative self-talk. This is because asking ourselves questions, such as “Can I do this?” will elicit reasons for doing something, create room for improvement, and produce better results.
Penny And Dime Lab Report
496 Words | 2 PagesIn this week’s lab we had to determine the density of a quarter, penny, and dime. My question was “How does is each coin?” Density is the amount of mass in an object. To find the density of each coin in this lab, we used a triple beam balance to find each coin’s mass and a graduated cylinder to find their volumes. With all this information, I can now form a hypothesis.
Penny In Free Fall
1022 Words | 5 PagesThese factors include the size and shape of the object. For example, the shape and size of paper of a rock differs from that of paper. But paper, because of it shape and size, would float down slower with more air resistance than the rock which has less air resistance. For example, in a well known article on the fall of an object, states, “More massive objects will only fall faster if there is an appreciable amount of air resistance present” (The Big Misconception 1). This shows the fall of an object does not care about mass but size and shape.
How Does Salva Give Up In A Long To Water
842 Words | 4 PagesA Long to Water is a novel by Linda Sue Park, which depicts the story about a Lost Boy of Sudan named Salva Dut Ariik. In the story, Salva tries to runaway from the Second Sudanese War, unfortunately leaving his family behind. There were times he felt lonely and depressed, but he was able to survive by having support from friends he made while running away, having determination, and bravery. Salva needed support from from friends while trying to overcome the Second Sudanese Wars. He needed it especially since he did not have any family going with him.
Galileo's Use Of Geometry Essay
1628 Words | 7 PagesThe use of mathematics in the beginning was used as something was not used for accuracy, but rather as something that could exercise the mind into rationalizing perspectives in a more logical way. The celestial heavens were considered more flawless and predictable compared to the ever changing and the visible deterioration on Earth. However to Plato, the importance of mathematics and unchanging patterns was to exercise the mind instead of explaining physical phenomena; basically, Earth is always changing, so the use of mathematical patterns will never be accurate enough because, in order to be accurate, Earth would need to stay consistent and unchanging, which Plato and others believed the heavens is such (P1, pg. 17). The approach of mathematics and physical explanations was also considered not to be related to each other mainly because of the accomplishments made by Aristotle.
Cold Water Lab
630 Words | 3 PagesThis experiment demonstrated water density because the cold water moved beneath the hot water, because it is denser. 5. Was your hypothesis supported or refuted? Explain.
Comparing The Chemical Reaction Between Pop Rocks And Soda Drink
298 Words | 2 PagesThis experiment is called jumping Pop Rocks. You first fill a glass with water that is 140 degrees fahrenheit. Then you pour the Pop Rocks into the glass. Since the Pop Rocks are infused with carbon dioxide they will tend to jump at the bottom of the glass, or maybe even reach the top of the glass once they dissolve.
Summative Lab: Base Jumping Experiment
893 Words | 4 PagesReliability: In my data, you could see that the 5.5 m drop took longer than 6m drop. However, I highly doubt that as I don’t believe my experiment is all that reliable (In the 5.5m fall, the parachute did hit the brick line which definitely would affect the drop time). Even though I did the 3x5 trials, however, my experiment had a lot of problems, that is why I suspect the reliability.
Roller Coaster Project Report
1284 Words | 6 PagesAs the marble slides down the first drop it will lose much of its potential energy corresponding to the loss of height. The marble subsequently gains kinetic energy – kinetic energy is contingent to the mass and the velocity of an object. The marble speeds up as it loses height, consequently, their potential energy is transformed into kinetic energy. Newton’s Second Law states that an object’s net external force is equal to its mass times its acceleration; simply, the acceleration is proportional to the force applied and also the mass of the object.
Egg Drop Lab Report
550 Words | 3 PagesTo find the momentum of the highest drop, the mass of the container with the egg inside it, 0.600 kg, was collected, and the final velocity of 15.0 m/s was calculated. This velocity was calculated by multiplying gravity by the time it took for the container to fall this distance. The final velocity and mass were then multiplied together to get the momentum, which is 9.00 kg m/s. Impulse is the change in an object 's momentum and can quantify the overall effect of a force acting over a specific time. To find the impulse for the highest drop, the value of the force exerted on the container was calculated by multiplying the mass with gravity, which equals 5.89 N. This force was then multiplied by the time it took for the drop, 1.53 s, which equalled an impulse of 9.01 Ns. The impulse and momentum is the same because, in a collision, an object experiences a force for a specific time interval that results in a change in momentum.
Effect Of Surface Area To Volume Ratio On The Rate Of Diffusion
1015 Words | 5 PagesWhat is the effect of surface area to volume ratio on the rate of diffusion of the colour from the agar jelly cube? INTRODUCTION: Diffusion is the movement of spreading particles from high concentration to low concentration in an environment such as a cell. This major procedure is used in cells to source them with nutrients, water, oxygen, and to transport unwanted wastes such as carbon dioxide out of the cell or to different cellular organelles.
Why Do More Water Come Out Of The Lowest Hole?
182 Words | 1 PagesMy hypothesis was correct because more water came out of the lowest hole. This hole probably had the most water pressure, which is why more water came out of the hole. It also had the longest stream length in the entire experiment. The hole that always produced the least amount of water was the highest hole, in the entire experiment. Based on my results, I think the water pressure is on the dam wall is greater at the bottom of the wall than at the middle or the top of the wall.
Why Boat Floats
68 Words | 1 PagesHow could a boat with a lot of people on it float on water but not a rock? Buoyancy is when something has the capability to float on air, water, or other fluids (in this case water). A boat floats when it has changed to an acceptable amount of water to equal its own primary weight. That is why a boat will float and a rock will sink.
Size Of A Parachute Affect The Falling Rate And Safety Of An Object?
463 Words | 2 PagesDoes the size of a parachute affect the falling rate and safety of an object? A parachute is a device used to slow down an object that is falling towards the ground. Without a parachute the gravity is more than air resistance. But as the parachute opens, the Air resistance increases. Now air resistance is more than gravity.
