Darwin’s Theory: Homologous, Analogous, Vestigial Features

What Darwin Observed Darwin sent specimens collected on his voyage back to England to be examined by experts Fossils collected were confirmed to be large versions of the present-day sloth and armadillo The Galapagos Island’s bird specimens were in fact many different species of birds Darwin originally thought they were just variations of the same…

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…
