Khan Academy Aprenda sobre eletricidade, teoria dos circuitos e introdução à eletrônica Nós também temos seções que te levam a por a mão na massa com utensílios domésticos, desde construir seu próprio robô até vídeos onde desmontamos utensílios domésticos para ver o que há dentro
Physics - Khan Academy The physics archive contains legacy physics content, and is not being updated with new content For our most up-to-date, mastery-enabled courses, check out High School Physics, AP Physics 1, and AP Physics 2!
Trigonometry - Khan Academy Learn trigonometry—right triangles, the unit circle, graphs, identities, and more
Khan Academy Learn AP Chemistry using videos, articles, and AP-aligned practice Review the fundamentals of atomic structure, intermolecular forces and bonding, chemical reactions, kinetics, thermodynamics, and equilibrium
Beta decay - Khan Academy During beta minus decay, a neutron in an unstable nucleus transforms into a proton, releasing a high energy electron and antineutrino in the process During beta plus decay, a proton in an unstable nucleus transforms into a neutron, releasing a high energy positron and neutrino in the process Beta particles carry away energy lost by the nucleus and are ionizing radiation
How is Khan Academy effective and different from other resources? Our Website With thousands of videos, it is easily the most exhaustive collection of instruction on the Internet allowing learners to know that they can fill in almost any of their "gaps" with the content on this site
