Fundamentals of Kinematics and Linear Motion
This comprehensive page covers fundamental concepts of kinematyka kinematics and linear motion, essential for understanding physics of motion.
The content explores various aspects of ruch prostoliniowy linearmotion and related concepts:
Definition: Distance droga represents the length of the path traveled, while displacement przemieszczenie is the shortest path between initial and final positions.
Vocabulary: Prędkość średnia averagevelocity is defined as the ratio of total distance traveled to total time taken.
Example: Converting units from km/h to m/s:
36 km/h = 36×1000/3600 = 10 m/s
Highlight: In uniform linear motion ruchjednostajnyprostoliniowy, velocity remains constant v=const, and equal distances are covered in equal time intervals.
Key mathematical relationships covered include:
- Average velocity: v = s/t
- Distance in uniform motion: s = v × t
- Acceleration in uniform accelerated motion: a = Δv/t
- Final velocity in accelerated motion: vk = vp + at
- Distance in accelerated motion: s = ½at² + vpt
Definition: Ruch jednostajny przyspieszony uniformlyacceleratedmotion occurs when velocity increases by equal amounts in equal time intervals.
Highlight: Vector quantities in motion include velocity, acceleration, and displacement, characterized by both magnitude and direction.
The page concludes with descriptions of accelerated and decelerated motion, emphasizing the relationships between instantaneous and average velocities in each case.
