Force, Electromagnetic Force, Strong Force and Weak Force; these forces play significant roles in shaping the Universe. Gravitational Force in regarding to cosmology is arguably the most compelling force with its large-scale of ability to illustrate how matters interact with each other in space. Electromagnetic Force is a critical force for living organism due to the fact that it is the force that holds atoms together to form molecules. Likewise, the Strong Force is severely important to life as it
Our roller coaster is about three and a half feet tall and two feet wide. It has one loop, two funnels, three turns, one five-part zig-zag, and one pulley leading from the end to the top, and four bells that rang and vibrated when the marble hit them. Our group divided the work by, assigning people jobs, then switching after a while. An example of that some people would score and other group members would fold, or some would build and others would test, and we took turns switching jobs. Something
of these forces is a pen being dropped. The force acting on the pen is the gravitational force. There is no other object under the pen to keep it from falling, so the pen will keep falling until it hits the floor. One of the most basic examples of how forces in physics work is a man standing. What keeps the man from simply falling forever or floating off into the air? The study of physics explains why the man stays on the floor. The man’s weight, which is his mass times the gravity, is pushing down
physics when it contradicted all previous laws of motion erected by Galileo and Newton. By mathematically manipulating these previous laws of motion, physicists in the nineteenth century were able to explain such phenomena as the flow of the ocean, the orbits of planets around the sun, the fall of rocks, and the random behavior of molecules in gases. At first, Einstein faced great opposition when he came up with his radical new theory because the previous laws of motion proposed by Galileo and expanded
Why do things fall when we drop them? How come we do not float as we would on the moon? Where do the colors of a rainbow come from? How long would it take to drive across Colorado if you are constantly changing speeds? All of these questions can now be answered, largely impart because of the great English philosopher, Sir Isaac Newton. In a time where religion was at war with science, Isaac Newton opened up people's minds to theories and reason. Isaac Newton was to be the starburst
contributes the three laws of planetary motion. Kepler studied the orbits of the planets and sought to discern some grand scheme that defined the structure of the universe according to simple geometry. Kepler also put together three laws of planetary motion: first, the planets rotate in elliptical orbits with the sun at one of the centers. The second states that all of the planets ‘sweep’ or cover equal areas in equal amounts of time, regardless of which location of their orbit they are in. This law is important
spinning wings gliding in mid-air propelled by the forces of torque and aerodynamic lift. The relationship between Newton's Laws of Motion and the flight of the Frisbee will be discussed. This paper will attempt to highlight and show the different physical motions involved behind the spinning edge of the Frisbee and the similar forces it shares with other heavier winged objects. Lastly, how major improvements in the redesign of the Frisbee contributed to its increased stability and precision in its flight

scientific method to make observations and test hypotheses is essential to unlocking the secrets of the universe. Energy is one of the most fundamental elements of the universe. Throughout history, man has endeavored to expose, understand, and explain how and why things work. This drive to expand our understanding eventually led to the development of the scientific method and what is commonly considered to be the king of the sciences, Physics. The effects of energy on the physical world are of great
------------------------------------------------- Rocket A rocket is a missile, spacecraft, aircraft or other vehicle which obtains thrust from a rocket engine. In all rockets, the exhaust is formed entirely from propellants carried within the rocket before use.[1] Rocket engines work by action and reaction. Rocket engines push rockets forwards simply by throwing their exhaust backwards extremely fast. Rockets for military and recreational uses date back to at least 13th century China.[2] Significant
