Center of mass

Background Gravity/Freefall: Every object on the Earth’s surface is pulled towards the center of the earth by the force of Gravity. Gravity causes all objects in Freefall to accelerate downwards at the same rate, regardless of the object’s mass. On Earth, acceleration due to gravity is constant of 9.81m/s^2. Therefore on Earth when air resistance is not present, all objects fall at the same acceleration of 9.81m/s^2. However, on the planet Vela Rani, the value of acceleration due to gravity is…

will transfer more energy into a stiff ball because less energy will be lost to deformation of the ball’s surface. Next, the Magnus Effect. Nothing is more exciting than when a soccer ball is curved into the goal. When a soccer ball is kicked off center, the ball starts to spin. It’s the same principle as a curveball in baseball. When the velocity of the ball drops, the Magnus Effect comes present. Finally, the Drag Force. The Drag Force occurs when a ball is kicked, and it travels through the…

more information on swimming and what the physics of it is. You will see swimming in a whole different way. Gravity is always affecting you while swimming. Even you don’t think it is. Force of attraction by which terrestrial bodies fall toward the center of the earth. Newton’s first law of motion has a part to do with swimming. An object in motion stays in motion until another outside force takes place. Static Force & Dynamic Force is also motions that take place in swimming. (physics of…

Introduction: Hot packs work by dissolving a salt, such as calcium chloride, in water to create an exothermic reaction. When salts are dissolved in water it requires energy to break their bonds apart, but energy is also released when the ions are surrounded by the water molecules. If more energy is released than is required to break the bonds, the reaction will be exothermic and will produce heat. In hot packs the water is kept separate from the salt, and when it needs to be activated, they are…

When work is put into the machine in step one, the toppling rule comes into effect because the first domino’s center of gravity is beyond the base of the domino, causing it…

acceleration, free fall. I will explain the definitions of each concept, so readers will be able to get real meaning as to why these concepts consist of cheer leading. Gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account. Therefore, cheerleading involves the force of gravity, because of the stunts,…

and Catholicism have a place in amongst over 35,000 Christian organizations (Jacobsen 7). I attended a mass at St. John 's Catholic Church and a service at St. John the Baptist Greek Orthodox Church, and the similarities and differences that I observed were extremely intriguing. Both services recite similar prayers, like the Nicene Creed and Our Father, and they celebrate the Eucharist during mass. While the Orthodox Church is demographically Greek, the Catholic Church represents a large white…

Physics can often explain many of the everyday activities of life; from playing football to ice skating to visiting an amusement park. Most people step into an amusement park excited for the thrill of riding all of the roller coasters without ever giving any thought to the physics behind the ride. There are several components of physics which contribute to the thrill of roller coasters, including gravitational forces, the law of conservation of energy, friction, centripetal force, and normal…

Newton’s law of universal gravitation [1] which states that any two bodies attract one another with a force which is directly proportional to the product of the two masses, and inversely proportional to the square of the radius measured between the centers of each object(F=(Gm_1 m_2)/r^2 ). [¬¬¬2] The first physical measurement of G was performed seventy one years after the death of Newton by Henry Cavendish using a torsion balance. [1] The method used by Cavendish, however,…
