Introduction- In theory, parachutes work because of the force of gravity. Gravity is a force of attraction between two objects, that is highly affected by size and proximity (gravity will have a stronger pull if the object are larger and close together). Gravity also differs from the mass of an object the more mass an object has the more gravity it will exert on the objects around it. When looking at really large masses, like the earth the gravitational pull becomes much greater because of its…

One of the most beneficial attack strategies in volleyball is the execution of a fast paced, downwards directional spike. A spike is proven to be one of the most effective shots in volleyball due to its force and difficulty for the opposition to return the shot. Through developments in modern technology in sport, biomechanics has become one of the most influential evaluative sources for skill analysis aiding improvements in sporting performance. A video analysis of my volleyball spike will be…

Isaac Newton was an English physicist and a Mathematician. He died on January 4, 1643, Woolsthorpe-by-Colsterworth United Kingdom. He died March 31, 1727, Kensington, London, United Kingdom. He famous for his law of gravitation. Isaac Newton had many discoveries and achievements. He generalized the binomial theorem. He made the world’s first working reflecting telescope. He created his three laws of motion. Isaac Newton was educated in Trinity college two…

Daily we are introduced to situations where the ability to mentally rotate an object or an image comes to good use. For example, imagine you are playing a game of Tetris. As the object is rapidly moving down your computer screen you have to mentally rotate it in order to see where the piece would fit best. In another scenario, imagine you are given a map to find directions around a city. After you locate yourself on the map, you next have to mentally rotate the map or yourself to decide which…

The mousetrap car is a simple machine but its take knowledge of the laws to be effective. Newton's three laws of motion are necessary for an acceptable length or distance category. Newton's first law of motion basically states that objects like to keep doing whatever it is that they are doing. If an object is sitting at rest on a table or rolling along the floor then that object will continue to sit on the table or roll along the floor until a force is applied to the object in order to cause a…

Newton’s Laws Sir Isaac Newton created his three laws in 1686 when he was only 43 years old. The three laws that he created were, 1) An object in motion stays in motion and an object at rest stays at rest unless acted on by an outside force. 2) F=ma, and 3) Every action has an equal and opposite reaction. Without these three laws there would be a huge misunderstanding in how things move, rise, and fall. Every time you hit a ball or bounce on a trampoline you are using one of Newton’s three laws…

The purpose of this experiment was to observe how the law of conservation of energy applies to a roller coaster system. In doing this we were able to determine the velocity of the cart as a function of its height upon the roller coaster, find the kinetic and potential energy for each trial of the cart and conclude energy loss due to friction. The results from part one concluded that as the roller coaster cart went down a hill the potential energy was converted into kinetic energy that resulted…

Clarkson said “It 's not how fast you are travelling which causes serious injury in a car crash, but it 's how fast that you stop.” During a crash the severity depends of how fast you break. Velocity, acceleration and Newton’s three laws play a vital role during a car crash. Sir Isaac Newton discovered the three laws of motion in 1686. Newton’s first law, or inertia, states that “an object at rest stays at rest and an object in motion stays in motion, with the same speed and in the same…

Could You…? Math Inquiry Pietro Could you run 0.8 kilometres in one minute? The fastest 100m sprint speed record is held by Usain Bolt , reaching the speed of 43.94 kph. 0.8 km is 800 meters. For you to run 800 meters in 1 minute you would need to reach the speed of Usain bolt speed: 43.94 x 800m= 35152 m/s. Though human endurance comes into play as well, as a person cannot run their top speed for more than 8 seconds. Usain Bolt was able to keep 95% of his top speed for 8 seconds during his…
