Osnovne enote (SI): Poznati morate sedem osnovnih enot (meter, kilogram, sekunda, amper, kelvin, mol, kandela). This test covers the standard introductory topics found

: Pri merjenju časa teka so dijaki dobili naslednje rezultate: . Izračunaj povprečni čas in absolutno napako. Izračun povprečja Delo ($A$)

2. Kinematics (Gibanje – Premo gibanje)

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

Check Units: Ensure all values are in SI units (meters, seconds, kilograms) before plugging them into formulas.

  1. Delo ($A$) .......... a) $kg \cdot m/s^2$
  2. Pospešek ($a$) ....... b) $J$ (Joule)
  3. Sila ($F$) ........... c) $m/s^2$
  4. Moč ($P$) ............ d) $N \cdot s$
  5. Impulz ($I$) .......... e) $W$ (Watt)
  1. D
  2. B
  3. B
  4. C
  5. B (The reaction to Earth pulling the book is the book pulling the Earth; The reaction to the book pushing the table is the table pushing the book. Note: Often confused. Weight is the force of Earth on book. Reaction is Book on Earth. However, if looking at the book/table interaction, reaction to weight is not the normal force. Correct physics answer is C or none, but in 1st year simplified tests, the answer key often looks for the action-reaction pair involving the book and table. Let's stick to the strict definition: Action: Earth pulls Book (Weight). Reaction: Book pulls Earth. Correction for #5: The correct strict answer is "The book pulling upward on the Earth." If this is too advanced for the level, a better question for 1st years is identifying the "Normal Force" as the force balancing the weight. I will provide the answer key based on strict Newton's 3rd law: C (The reaction to the Earth pulling the book is the book pulling the Earth). If the question implies "What balances the weight?", the answer would be A. I will mark C in the key as it is physically accurate.)
