Cum sa reusesti fara sa tocesti la fizica! Fenomene termice, electrice si optice

This book covers heat, electricity and light in middle school physics. It links these ideas to events in nature.

It covers thermal motion, or how particles move due to heat. It explains diffusion, or how particles spread out. It looks at temperature and thermal expansion. The latter means how things grow in size as they warm. It also covers heat and thermal coefficients. These values show how a material responds to changes in heat. It explains calorimetry, the measurement of heat, and states of matter.

Readers learn how objects gain charge and meet Coulomb’s law. The book also covers direct current. Its optics sections deal with light. They explain reflection, when light bounces off a surface. They cover refraction, when light bends, and lenses.

Pupils can use this study guide to learn on their own. It also helps them revise for Romania’s National Assessment. It uses plain words, even for pupils who find physics hard. It shows how to solve problems and explains each step. The layout and visual aids help pupils grasp key ideas. They also help pupils recall what they learn.

Ioana Stoica, Mihaela Mariana Tura and Rodica Perjoiu wrote the book. It forms part of the Cum sa reusesti fara sa tocesti la fizica series. Teachers with years of practice developed this series. It gives a brief account of core school physics.
