Electricity: Coulomb’s Law, Force, Energy, Potential

Intrinsic property of particles that comprise matter Point charge: charged particle with negligible size Mass and charge are independent from each other Positive Charge (q+) and Negative Charge (q-) Coulomb’s Law Magnitude of electric force between two charged spheres is proportional to the absolute amount of charge on each sphere, and is proportional 1/r2 where…

Induction: Induced & Permanent Charging

Induction: Induced & Permanent Charging Static electricity can be generated through: Friction, Conduction, INDUCTION Induction INDUCTION involves the movement of electrons in a neutral object when a charged object is brought close to the neutral object. The movement occurs WITHOUT DIRECT CONTACT between objects. Induced Charge Separation/ Temporary Charging When a negatively charged rod is…

NASA Mission to Mars: Probes, Design, Dangers

Introduction About 110 years ago, when McKinley was President of United States, the concept “Man on Moon” was an insignificant consideration to society and to the government’s budget. In present day, space constitutes a large portion of the 2011 government budget plan.  President Barack Obama is predicting a manned Mars mission to orbit the planet…
