Kinematyka Wzory - Essential Formulas for Motion
This page presents key formulas for ruch jednostajny prostoliniowy uniformlinearmotion and ruch zmienny variablemotion. For uniform linear motion, the velocity V is constant, and the displacement S is calculated by multiplying velocity and time t. In variable motion, acceleration a is introduced, which changes the velocity over time.
Definition: Ruch jednostajny prostoliniowy is motion with constant velocity in a straight line.
The formulas for uniform linear motion are:
For variable motion, the following equations are provided:
- a = Vk−Vp / t
- V = V₁ + a • t
- S = V₁ • t + at2 / 2
- V = V₁ - a • t
- S = V₁ • t - at2 / 2
Highlight: The equation S = V₁ • t + at2 / 2 is particularly important for solving problems involving ruch jednostajny przyspieszony.
Example: In ruch jednostajny przyspieszony, if a car starts from rest and accelerates at 2 m/s², after 5 seconds it will have traveled S = 0 • 5 + 1/2 • 2 • 5² = 25 meters.
