Galilei Force Theory

Great 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

    Everyone knows that heavier objects require more force to move the same distance as lighter objects. The second law gives us an exact relationship between force, mass, and acceleration. It can be expressed as a mathematician equation, the formula is F=MxA. Newton’s third law is for every action there is an equal and opposite reaction. This means that for every force there is a reaction force force that is equal in size, but opposite in direction.…

    This law is when a force is being put on an object but it isn't balanced nor equal. When Bennett pushes off the block he is no longer at rest therefore unbalanced forces are acting upon him. Bennett is the object and his mass compared to the block’s mass causes his acceleration to happen when he pushes off the block and into the air. There is also a friction force when he is positioning his feet on the block to move his feet kinetic friction is in action.…

    Weight, distance, and velocity have a lot to do with gravity. To start it off, the gravitational pull of a planet or the force exerted from the object is called weight. Weight is taken by the force of the object due to gravity. The object’s weight keeps it in the center due to the force that the earth has. After that the measurement from one point to another is called distance.…

    Plato once said, “Astronomy compels the soul to look upwards and leads us from this world into another.” Obviously, astronomy has always been an interest to mankind. We look up into the night sky and feel an urge, something pulling us towards the stars. Many people have been influential in discoveries involving the stars and the planets beyond. From Galileo Galilei to Stephen Hawking, we have learned and discovered amazing things about the universe, and in recent discoveries we have wondered if we can go to another planet.…

    What forces that you have learned about in this course do you see in action? I learned about a few forces so far throughout this video. I learned about unbalanced forces by seeing how the dogs used an inclined plane. Once a dog goes up an incline, gravity will take place and the incline plane will be uneven. This leads to unbalanced forces.…

    The airboat is related to Newton first law because since the boat is in the water it is in motion and it will remain in motion unless something stops it from being in motion it will be an unbalanced force. The second law is related to the airboat because the airboat is moving with a certain amount of force. Newton’s third law is related to the airboat because when the propeller is turned on it throws air behind the boat, the action creates an equip and opposite reaction pushing the boat forward.…

    Drag force is an aerodynamic force which acts parallel and opposite to the motion of the object when it moves through a fluid. It is caused by friction and differences in air pressure. There are many factors can affect the magnitude of drag force as with aircraft lift. The drag depends linearly on the shape and size of the object moving through the air.…

    Investigation Hooke’s Law AIM: To investigate how a spring behaves when a force of load stretches it. To figure out the relationship between the loads added to spring and the extension of spring. HYPOTHESIS: I think that as the load added to spring increases, the extension of the spring will increase. The relationship between them will be directly proportional. The formula of these two variables might be F=kx.…
