Razumevanje sistematičnih in naključnih napak ter pravilno zapisovanje fizikalnih količin z ustreznim številom orientacijskih (signifikantnih) mest.
Isaac Newton’s domain. This is usually the second test or the second half of the first semester.
Razlikovanje med količinami, ki imajo le velikost (npr. čas, masa), in tistimi, ki imajo tudi smer (npr. sila, hitrost). 2. Kinematika: Opisovanje gibanja
$F = ma \Rightarrow a = F/m = 50 / 20 = 2.5 \text m/s^2$. 3. c) Acceleration would decrease because $a = F/m$. If mass doubles, acceleration halves.
Sila in pospešek imata smer. Če sila deluje v nasprotni smeri gibanja, je njen pospešek negativen. fizika 1 letnik gimnazije test
80% of wrong answers come from forgetting to convert.
Fizikalne količine, sile (prvi test v prvem letniku gimnazije)
I'll also search for "fizika 1 letnik gimnazije test 2". relevant.
: When an object speeds up or slows down at a constant rate ( : A special case of acceleration where (often rounded to for simpler gymnasium tests). : Interpreting graphs. The area under a graph represents the distance traveled. 3. Dynamics (Forces and Newton's Laws) This section explains objects move the way they do. Newton’s First Law (Inertia) Razlikovanje med količinami, ki imajo le velikost (npr
A cyclist is moving at 10 m/s when they begin to brake. The bicycle comes to a complete stop after 5 seconds . a) Calculate the acceleration (deceleration) of the bicycle. b) Calculate the braking distance required for the bicycle to stop.
This test covers the standard introductory topics found in most European gymnasium curricula: and Dynamics (Forces) .
A common pitfall on tests is forgetting that always acts opposite to the direction of motion. Drawing a Free Body Diagram (sketching all the force arrows on an object) is the best way to ensure you don't miss a variable in your equations. Success Strategy
Vedno zapišite, kaj je znano in kaj iščete. Podatke takoj pretvorite v osnovne SI enote. Analiza grafov: Na testih se pogosto pojavi energija) vas čaka na naslednjem testu?
): A classic test question asks you to interpret a graph. For instance, the represents the distance traveled. Being able to translate a story into a graph (and vice-versa) is a sign of true understanding. Dynamics: Newton’s Laws
Premo enakomerno gibanje, premo enakomerno pospešeno gibanje, grafi gibanja (s-t, v-t, a-t).
Vedno izpišite podane količine in tisto, kar iščete.
Katero (npr. kinematika, sile, energija) vas čaka na naslednjem testu?
