Émilie du Châtelet (1706–1749) was the first to publish the relation for kinetic energy , derived from the experimental observation of objects dropped into clay.. (Portrait by Maurice Quentin de L
For two pairwise interacting point particles, the gravitational potential energy is the work that an outside agent must do in order to quasi-statically bring the masses together (which is therefore, exactly opposite the work done by the gravitational field on the masses): = = where is the displacement vector of the mass, is gravitational force acting on it and denotes scalar product.
The gravitational potential (V) at a location is the gravitational potential energy (U) at that location per unit mass: =, where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity.
The first of these systems to be revealed was the Flybrid. [4] This system weighs 24 kg (53 lbs) and has an energy capacity of 400 kJ after allowing for internal losses. A maximum power boost of 60 kW (81.6 PS, 80.4 HP) for 6.67 seconds is available.
Any atmospheric circulation system, whether it is a small-scale weather system or a large-scale zonal wind system, is maintained by the supply of kinetic energy.The development of such a system requires either a transformation of some other form of energy into kinetic energy, or the conversion of the kinetic energy of another system into that of the developing system.

Typically, amortized analysis is used in combination with a worst case assumption about the input sequence. With this assumption, if X is a type of operation that may be performed by the data structure, and n is an integer defining the size of the given data structure (for instance, the number of items that it contains), then the amortized time for operations of type X is defined to be the ...
William Henry Harrison (February 9, 1773 – April 4, 1841) was the ninth president of the United States, serving from March 4 to April 4, 1841, the shortest presidency in U.S. history.
Brenda Mae Tarpley (born December 11, 1944), [2] known professionally as Brenda Lee, is an American singer.Primarily performing rockabilly, pop, country and Christmas music, she achieved her first Billboard hit aged 12 in 1957 and was given the nickname "Little Miss Dynamite".
