Fizika 1 Letnik Gimnazije Test Review

Če prvo telo deluje na drugo s silo, deluje drugo na prvo z enako veliko in nasprotno usmerjeno silo. Vrste sil: Teža ( ), sila podlage ( FNcap F sub cap N ), sila trenja ( ), sila vzmeti (Hookov zakon: ) in upor. D. Delo, energija in moč Mehansko delo ( ): Produkt sile in premika v smeri sile ( ). Če sila deluje pod kotom: Kinetična energija ( Wkcap W sub k ): Energija gibajočega se telesa ( Potencialna energija ( Wpcap W sub p

To je temeljno poglavje, brez katerega ne morete reševati nalog v nadaljevanju leta.

For every dynamics or kinematics problem, draw a force diagram or a simple coordinate system.

This is the largest section. Focus on and uniformly accelerated motion .

Energija se ne more uničiti ali nastati iz nič, le pretvarja se iz ene oblike v drugo. Moč: Hitrost opravljanja dela ( 📝 Najpogostejši tipi nalog na testu

Avtomobil začne pospeševati iz mirovanja s stalnim pospeškom

You can find practice materials and past exams on specialized Slovenian educational portals: For clarifying terminology.

The key is to move beyond passive reading. Physics is learned by doing, so here’s how to prepare effectively.

Da na testu ne bo nepotrebne panike, upoštevajte naslednje korake:

physics test assesses your ability to convert units, interpret motion graphs, and apply Newton’s laws to solve basic mechanical problems.

: For every action, there is an equal and opposite reaction. Common Forces is the coefficient of friction and cap F sub n is the normal force. Elastic Force : Hooke's Law, Example Problem Structure A typical test problem might look like this: A car starts from rest and accelerates uniformly at

. Izračunaj njeno gostoto in jo izrazi v osnovnih enotah SI ( kg/m3kg/m cubed Najprej izračunamo volumen kocke: Izračunamo gostoto v g/cm3g/cm cubed Pretvorba v kg/m3kg/m cubed , rezultat pomnožimo s 1000. Odgovor: Gostota kocke je Primer 2: Kinematika (Pospešeno gibanje)

: Before solving a problem, draw a free-body diagram. Visualizing forces helps you set up the equations correctly.
