Definition: Acceleration is defined as the rate of change of velocity with respect to time, remaining constant in uniform accelerated motion.

Highlight: In linear motion, the direction of acceleration vector aligns with the direction of motion.

Example: Forces acting on an object are illustrated, including gravitational force (Fg), normal force (Fs), pulling force (F), and friction force.

Quote: "When the resultant force is constant, the body moves with constant acceleration."

Definition: Distance traveled can be calculated as the area under the velocity-time graph.

Example: A detailed problem shows how to calculate distance when initial velocity is 20 m/s and final velocity is 30 m/s over 40 seconds.

Highlight: The formula s = ½$v₁ + v₂$t is used for calculating distance in uniform accelerated motion.

Vocabulary: Obliczanie drogi z wykresu v$t$ refers to calculating distance from a velocity-time graph.

Definition: Uniform accelerated motion occurs when velocity changes by equal amounts in equal time intervals, resulting in constant acceleration.

Highlight: The velocity-time graph demonstrates how velocity changes linearly with time in uniform accelerated motion.

Example: A graphical representation shows velocity increasing from 0 to 30 m/s over a time period, illustrating constant acceleration.

Vocabulary: Ruch jednostajny zmienny refers to motion with constant acceleration or deceleration.
