Universal Gravitation Apples had a significant contribution to the discovery of gravitation. The English physicist Isaac Newton (1642-1727) introduced the term "gravity" after he saw an apple falling onto the ground in his garden. "Gravity" is the force of attraction exerted by the earth on an object. The moon orbits around the earth because of gravity too. Newton later proposed that gravity was just a particular case of gravitation. Every mass in the universe attracts every other mass. This is the

[pic] The product of average force and the time it is exerted is called the impulse of force. From Newton’s second law [pic] the impulse of force can be extracted and found to be equal to the change in momentum of an object provided the mass is constant: |[pic] |Calculation | The main utility of the concept is in the study of the average impact force during collisions. For collisions‚ the mass and change in velocity are often

Centripetal force (from Latin centrum "center" and petere "to seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre

How competitive forces shape strategy Pflicht 4. (5Forces) " 1 von 3 While one some- times hears executives complaining to the contrary‚ intense competition in an industry is neither coincidence nor bad luck. Moreover‚ in the fight for market share‚ competition is not manifested only in the other players. Rather‚ competition in an industry is rooted in its underlying economics‚ and competitive forces exist that go well beyond the established combatants in a particular industry. Customers

An electron gun fires electrons into a magnetic field directed straight downward. Find the direction of the force exerted by the field on an electron for each of the following directions of the electron’s velocity: (a) horizontal and due north; (b) horizontal and 30° west of north; (c) due north‚ but at 30° below the horizontal; (d) straight upward. 2.

Title: Centripetal Force Tools and Equipments: nylon cord‚ different weighing hanging masses‚ stopwatch‚ meter stick. Purpose: To be able to determine the relationship between centripetal force‚ mass‚ velocity‚ and the radius of orbit for a body that is undergoing centripetal acceleration. To investigate the dynamics of uniform circular motion. Specifically the relationships among the centripetal force‚ the accelerated mass and the radius of rotation. Procedure: THEORY:

Organizational Behavioral Forces There are many forces that dictate the organizational behavior within an organization. The organizational behavior will tend to shift based upon the different demands both internally and externally. Internal and external factors have an equal importance within organizations and will have different effects and outcomes on an organization. In this paper we will compare four very different organizations and demonstrate the effect four factors have on the organizational
