Galilei Force Theory

Amazing Essays
The invisible being that created the push or pull of an object has been a law of science since the early ages. The first scientists to study this entity was Ancient Greek scientists Archimedes. His theory is now referred to as Archimedes 's principle, or the law of fluid mechanics. It implies that there is force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. He hypothesized this theory while in the bath. Unfortunately his theory only covered fluid mechanics and didn’t elaborate completely on force. However he was one of the first scientists to discover buoyancy and the displacement of fluids. By 17th century Italian astronomer Galileo Galilei …show more content…
There are two main fractions of Force, each with their own subdivisions. The first division is Contracted forces which are forces that are a result of two interacting objects and are physically contacting each other. There are five types of contracted force; frictional force, tension, force, air resistance force, applied, force, and spring force. Frictional force occurs when two parallel object’s surfaces come into contact with one and another heading in a perpendicular direction. In english this means when two surfaces come in contact with one and other they create a friction. An example of this would be the movement of furniture. When you push a table across the floor, the surface of the table and floor are creating friction through your applied force. After is tension force, a force that passes through a string, rope, cable or wire when it is being pulled tight by forces acting from other ends. Tension force is commonly found in circuses, tight rope walkers apply a force to the rope which causes the opposite end of the rope to tighten. Next contract force is air resistance force otherwise known as drag force. It is a type of frictional force that acts upon objects as they travel through the air. A common example of this would be the sail of a sail boat. When the wind meets the sail,it resists the direction thus causing air resistance which in turn pushes the boat forward. Last of the contracted forces is Spring Force. Spring Force is force applied by a stretched spring upon any object that is

    this can lead to friction. The shear drag is proportional to the rate of the arrow within the air, however, opposite in direction. Fd = - bv. kind drag is because the arrow flies through the air, the shear drag can produce eddies. These eddies, that area unit the whirling of the air within the reverse current, can kind turbulent wakes, therefore, leading to kind drag.…

    This gives rise to turbulent flows and varying pressures. As the wind passes past a bluff body, it undergoes boundary layer separation, which causes imbalance in pressure. This results in a phenomena, specific to bluff bodies, called the vortex shedding. The wind leaving the body, which undergoes vortex shedding causes alternating wind pressures at the rear end of the body. This alternating pressure forces the body to sway to and fro respectively.…

    The factors that affect the drag coefficient is the shape of the body, the roughness of the surface, the viscosity of the fluid and compressibility of the object. The viscosity of the fluid introduces the Reynold Number. In Engineering, a key concept to understand is the Reynolds Number. It is the ratio inertial forces (resistance to motion) compared to the viscous forces (fluid 's internal resistance to flow). It is dependent of the velocity, density characteristic length and dynamic viscosity.…

    (Zmuida, n.d) Wind can impel ocean currents to move due to resistance. Contingent on the Earth's rotation, winds can move to the top surface of the ocean and creating the surface of the currents. Then, a gyre will formed due to the surface of the current. A gyre is a spiral movement that formed on an ocean's surface. (Zmuida, n.d) Therefore, currents can be moved by tidal patterns.…

    This is generally done by compressing or stretching the spring. By compressing the spring, the spring is displaced from equilibrium and moved towards the right, automatically assigning a sense of direction causing negative displacement. When the spring is stretched, the mass is displaced from equilibrium in the opposite direction causing positive displacement. Regardless of how the spring is distorted, the restoring…

    When a liquid is in a closed vessel under pressure, each particle of the liquid exerts pressure on other particles. The walls of the container and the surface that is tempting the pressure, exerts push against them in reaction. These forces are actually the remaining result of a wide-ranging number of intermolecular forces and impacts between those molecules. Representation: Stress is often notified by a Greek symbol sigma (σ). When we discuss stress, we have to discuss strain also, as both are related to each other.…

    Medium is the material in which a wave travels. Mechanical Waves When a source of energy causes a medium to vibrate, a mechanical wave is formed. Mechanical waves require a medium to travel. There are two different types of mechanical waves: longitudinal and transverse waves. The major difference between them is that the transverse waves the displacement of the medium to the direction of propagation of the wave is perpendicular and in the longitudinal is parallel.…

    The sails of the boat contain some of the wind energy (provided by the fan) and use it to accelerate in the same direction it received this energy. The boat also shows that once all this energy is channelled, it will begin to move at a constant velocity. The fan resembles an external force acting on an object. In relation to forces, this shows that an object can only be moved as a result of an external force acting on it. The boat was designed according to Newton’s second law of motion.…

    Potential energy begins the transfer of energy on the first hill. A chain motor pulls the cars to the top of the hill creating potential energy. Potential energy being defined as the energy determined by its position compared to that of its surroundings. The potential energy is built up due to the height of the roller coaster. Although some of the energy is lost it is eventually turned into kinetic energy.…
