Anti-gravity is the idea of creating a place or object that is free from the force of gravity. It does not refer to the lack of weight under gravity experienced in free fall or orbit‚ or to balancing the force of gravity with some other force‚ such as electromagnetism or aerodynamic lift. Anti-gravity is a recurring concept in science fiction. In Newton’s law of universal gravitation‚ gravity was an external force transmitted by unknown means. Under general relativity‚ anti-gravity is impossible

The Centre of Gravity & its relationship to the Application of Sports Massage Introduction Every object has a centre of gravity‚ which‚ when combined with other factors such as the line of gravity‚ enables an object to balance. If a person or object moves or changes shape‚ the centre of gravity will also move. This is important to remember when discussing sports massage as the therapist is constantly moving‚ making them vulnerable to being unbalanced or unstable. So to be able to conduct a safe

Specific gravity What is specific gravity? Archimedes discovered that the weight of body in air minus its weight in water is equivalent to the weight of the water displaced by the body. Specific gravity is defined as "The weight of a body compared with the weight of an equal amount of pure water at 4°C (4°C is the temperature at which water is densest). When a body is placed in water‚ the volume of water displaced is equal to the volume of the body. When the body is placed in water that it

Introduction: Specific gravity or relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. Temperature and pressure must be specified for both the sample and the reference. The following formula is used- Specific gravity= density of sample/density of same volume of water. Specific gravity is commonly used as a simple means of obtaining information about the concentration of solutions

Herden Abstract: This report will investigate two theories about gravity‚ these including Aristotle’s theory‚ of which states‚ the heavier the object‚ the faster it falls‚ alongside Galileo’s trialed theory; Two object of different masses‚ when dropped from the same height will reach the ground at the same time. Correspondingly‚ this investigation shall trail and prove correct Galileo’s theory of gravity. Introduction and Background: Gravity is the attraction

Center of Gravity The point in a body or system of bodies at which the whole mass may be considered as concentrated. When an object’s weight is distributed uniformly‚ the center of gravity lies at its geometrical center. For irregular shaped objects‚ the center of gravity is near to the concentration of its mass. Equation: Where: X= center of gravity xi= distance of the objects from fulcrum or arbitrary axis mi= mass of the object Sample Problems 1.) Suppose your lab partner has

These countries have the largest gross domestic product (GDP) in Europe. * GDP measures the value of goods and services produced in an economy. In fact‚ the size
