Physics Formulas and Concepts
This page presents crucial formulas and concepts related to ruch jednostajny prostoliniowy (uniform linear motion) and dynamics, including Newton's laws of motion.
Uniform Linear Motion
The section on uniform linear motion introduces the basic formula:
v = 1/2 √-stała
This equation relates velocity (v) to a constant value, highlighting the nature of uniform motion.
Definition: Ruch jednostajny prostoliniowy refers to motion in a straight line at a constant speed.
Accelerated/Decelerated Linear Motion
For accelerated or decelerated motion, the following formulas are presented:
a = √k-Up
Uk = Vpt at
These equations involve acceleration (a), initial velocity (Up), and time (t).
Highlight: Understanding the difference between uniform and accelerated motion is crucial for solving ruch jednostajny prostoliniowy zadania (uniform linear motion problems).
Newton's Laws of Dynamics
The page introduces the three fundamental laws of dynamics, also known as zasady dynamiki Newtona:
-
First Law of Dynamics: F₁s = 0
This law states that an object remains at rest or in uniform motion unless acted upon by an external force.
-
Second Law of Dynamics: a = F/m
This law relates force (F), mass (m), and acceleration (a).
Example: The formula F = ma is a key dynamika wzory (dynamics formula) used in many physics calculations.
-
Third Law of Dynamics: action = reaction
This law states that for every action, there is an equal and opposite reaction.
Vocabulary: Siła wypadkowa (resultant force) is mentioned as the force that replaces all component forces in a system.
The page concludes with a note on the unit of force: [F] = 1 kg⋅m/s², which is equivalent to 1 Newton (1N).
Highlight: These dynamika wzory (dynamics formulas) are essential for solving problems related to motion and forces in physics.
