Rodzaje Ruchów w Kinematyce

This page explores various types of motion, providing a comprehensive overview of rodzaje ruchów fizyka and podział ruchu ze względu na prędkość.

1. Uniform Linear Motion $Ruch jednostajny prostoliniowy$: Constant velocity $v = const.$ Zero acceleration $a = 0$ Key formulas: v = s/t and v = Δr/t

Example: In uniform linear motion, the distance-time graph is a straight line, with the slope representing velocity.

2. Uniformly Accelerated Motion $Ruch jednostajnie przyspieszony$: Changing velocity $v ≠ const.$ Constant acceleration $a = const., a > 0$ Velocity increases over time

Highlight: The area under the velocity-time graph represents the distance traveled in uniformly accelerated motion.

Ruch Jednostajnie Opóźniony i Wzory Kinematyczne

This page focuses on uniformly decelerated motion and introduces key formulas for various types of motion, expanding on kinematyka wzory and ruch zmienny wzory.

Uniformly Decelerated Motion $Ruch jednostajnie opóźniony$:

• Changing velocity $v ≠ const.$
• Constant acceleration $a = const., a < 0$
• Velocity decreases over time

Key formulas for uniformly accelerated and decelerated motion:

1. Distance: s = v₀t + ½at²
2. Acceleration: a = Δv/t = $v_k - v₀$/t
3. Final velocity: v_k = v₁ + at $for accelerated motion$
4. Final velocity: v_k = v₁ - at $for decelerated motion$

Highlight: The area under the velocity-time graph represents the distance traveled, while the slope of this graph represents acceleration.

Kinematyka - Podstawy Ruchu Prostoliniowego

Kinematyka, a crucial branch of physics, focuses on the study of motion without considering its causes. This page introduces fundamental concepts and definitions essential for understanding motion.

Definition: Kinematyka is the branch of physics that studies motion without considering its causes.

Key concepts introduced include:

1. Motion: Defined as the change in position of an object relative to a reference frame.
2. Material point: A model of an object where size is ignored but mass is considered.
3. Path of motion: The line along which an object moves, classified as: a) Linear $prostoliniowy$ b) Curvilinear $krzywoliniowy$

Highlight: Motion is classified based on velocity as: a) Uniform motion $ruch jednostajny$ where velocity is constant b) Variable motion $ruch zmienny$ where velocity changes, either uniformly or non-uniformly

The page also introduces key kinematic quantities:

• Speed $scalar$
• Velocity $vector$
• Distance $scalar$
• Time $scalar$
