Mass Object Affect Falling Speed Liquid Environmental Sciences Essay

Mass Object see locomote Speed Liquid Environmental Sciences EssayThe purpose of this experiment was to determine how a skunk of an butt would affect its travel when sinking through glycerol or weewee. I became interested in this idea when watching a movie on submarines which are designed to be able to amaze off through water at high speeds.I knew before I started my investigation that glycerin is heavier than water, in that locationof glycerin will slow down the speed of a move intent glassive glass. I also knew that the heaviest object give-up the ghosts faster than the light objects due to my knowledge and observation of a f eaching stone which is apparently faster than a falling bird feather.Why the investigation is important?The problem was important to wonder beca wasting disease when I was watching a movie ab pop out submarine, I wondered about submarine as being a heavy object and how it travels through water so smoothly with very high speed. I was trying to see if objects mass affects the speed it travels through water.The speed of falling weights through water and glycerin is tested in this research. I think that the heaviest weight will be the first to fall. The materials used in my experiment are cylinder, 3 diametrical weights, stopwatch, water and glycerin. The results turned out to be that the heaviest weight reached the croupe of the cylinder first, while the second was the middle weight and the lightest weight was the last. thereof my hypothesis turned out to be correct as the heaviest weight fell in the shortest time. I get down also find that it is really difficult to maintain the same amount of extract on each weight, as a workaround the same dropper dropped the 3 weights from the same distance. For further research enhancement, I suggest that weight should have been hanged on U shape wood board freely and use scissors to release the weights to examine that no external attract was added to the weight. Also tested weights need to be of the same shape and coat to eliminate whatever additional variables. I have really gained caboodles of information about gravity, weights and bland friction.Background InformationAristotle theorized that heavy objects accelerate faster than lighter ones.Galileo observed the falling of varies masses from the contention Tower of Pisa. He noticed that the acceleration is independent of their mass which leads him to a conclusion that a falling or rolling objects appeared to accelerate at the same rate independently of their mass.Aristotles theory was establish on the philosophy of logic in that it seemed obvious that heavier objects would fall faster than light objects, while Galileos theory was based on actual observation and experimentation.Galileo Italian physicist, mathematician and philosopher Aristotle Greek philosopher (384 BC 322 BC) (15 February 1564 8 January 1642)Summarizing Aristotles View and Galileos experimentAristotle held that there are two kinds of motion for objects, natural and unnatural. Unnatural (or violent) motion is when something is being pushed, and in this case the speed of motion is proportional to the force of the push. Natural motion is when something is seeking its natural place in the universe, much(prenominal) as a stone fall.For the natural motion of heavy objects falling to earth, Aristotle stated that the speed of fall was directly proportional to the weight, and indirectly proportional to the density of the medium the body was falling through.Galileo has done dual experiments to answer the question that heavy objects fall at practically the same rate.Observation wont lonesome(prenominal) answer this question as all objects fall in addition fast. To make all kind of bar of the speed, the motion must somehow be slowed down.Thats why I have selected Glycerin instead of water to slow down the speed of a falling objectMass and WeightThe mass of an object is measure of the amount of matter in the object. While the weight of an object is defined as the force of gravity on the object and may be considered as the mass times the acceleration of gravity, w= mg. While the real weight of a humankind is determined by his mass and the acceleration of gravity.Falling objects holds a force thats much high than its weight.WeightlessnessWhile the real weight of a human is determined by his mass and the acceleration of gravity, ones real or effective weight comes from the fact that he is supported by other objects like floor, chair and table. If all the supported objects are removed all of a sudden the person will begin to fall freely and he feels weightless Thus weightlessness refers to a state of being in free fall.The state of weightlessness can be reached in quite a lot of ways, all of which involve significant physical principles as seen in below figures.What is clash?A friction is the wicked force of all motions. Regardless if you throw an object to the right the friction switch es the direction of the falling object so we call it the opposite wicked force.Friction is actually a force that appears whenever two things are rubbed against each other. Although two objects might look smooth, microscopically, theyre very rough and jagged, as seen in below pictureAs objects slide against each other, a coquette and drag force against each other is produced. This is where friction comes from. Friction is useful as it has a lot to do with our daily life. Without it, we wouldnt be able to walk, sit in a chair, climb stairs, or use a mouse to surf the web. Everything would just keep slipping and falling all over the place. silver-tongued frictionFluid friction is what happens with liquids and gases (In Physics, liquids and gases are both called fluids)Fluid friction depends on how thick the fluid is (its viscosity), objects shape and objects speed.Aircraft and car designers want to reduce drag, so that they can go fast without having to waste too much fuel.To reduce friction, we need a shape that the fluid can flow past well and smoothly. This tends to mean using long, pointed, streamlined shapes.Speed, Acceleration and ForcesSpeed is how fast an objects position changes with time at any given moment. A car traveling 70 KM per hour is traveling faster than a car with a speed of 40 KM per hour. Average Speed is the total distance traveled by the amount of time.The description of both speed and direction of a moving object is its velocity. devil objects can have the same speed but different velocities if they are moving in different directions.When a moving objects velocity increases with time, the object is accelerating. The acceleration of an object falling freely near Earths airfoil due to gravity is called a G.A force is a push or pull exerted by one object on another. Forces change the motion of objects.Friction is a force that opposes the motion of an object sliding over another. Friction acts any time the surfaces of objects are in con tact.When an object moves through a gas, such as air, or any liquid, there is forces that resist motion. This force is called drag force. As an object moves through the air, the air molecules hit into it (a drag force) and cause the object to slow down. Drag force depends on speed. The faster the speed, the greater the drag force.Gravity is a force of attraction that exists between all objects with mass. The force of gravity between two objects depends on the masses of the two objects and the distance between the objects. The closer the objects are to each other, the stronger the force of gravity exerted on each other. The force of gravity between Earth and any other object is called the weight of the object.Sources of ErrorThe sources of illusion in this project were mainly human error the dropper can not exactly maintain the same external force on dropping the weight, the stopwatch holder could waste some seconds before stopping the watch. I have encountered and taken tuition of another error by changing the research topic slightly as I wanted to test the speed of falling balls with different weights (ping pong, Squash and Golf) in glycerin, but the ping pong and the squash racquets ball float in the glycerin. That is why I used 3 different weights instead of the 3 balls.Applications of investigationsI think that engineers creating submarines or any under water traveling objects will greatly get from my research.Further ResearchNext time I will try to be more veracious in my experiment by using different weights with same size and shape and try to get rid of human error as much as possible.
