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

CEMB 121 MECHANICS OF MATERIALS LABORATORY EXPERIMENT (NO.2 (a)) SHEAR FORCE I SUMMARY Shear Forces occurs when two parallel forces act out of alignment with each other. For example‚ in a large boiler made from the sections of sheet metal plate riveted together‚ there is an equal and opposite force exerted on the rivets‚ owing to the expansion and contraction of the plates. The shearing force (SF) at any section of a beam represents the tendency for the portion of the beam on one side of

districts into quartiles of high and low poverty‚ which are used for further analyses and determination of funding‚ staffing‚ and other needs (CSDE). The simple measure of poverty is when a family’s income is not meeting its needs. The underlying causes of poverty are much more convoluted‚ relating to the distribution of government power‚ a continuously widening income gap‚ differences in cultural attitudes and ideologies‚ and inequalities in wealth and education. Other social conditions tend to

Bullying is not illegal in the United States. Although it has grown national awareness‚ it is still very much a serious problem today. All types of bullying have created a learning disadvantage among our youth. "Most bullying takes place in school‚ outside on school grounds‚ and on the school bus. Bullying also happens wherever kids gather in the community." Students victimized often experience low self-esteem and isolation‚ a crippling fear of rejection and an increase in social anxiety‚ therefore
