Equation of Motion Using Final and Initial Position
Equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time.
The final speed squared equals the initial speed squared plus twice the acceleration times the difference between the final and initial positions.
Formula
![Copy to Clipboard QuantityVariable[Subscript["v", "f"], "Speed"]^2 == QuantityVariable[Subscript["v", "i"], "Speed"]^2 + 2*QuantityVariable["a", "Acceleration"]*(QuantityVariable[Subscript["x", "f"], "Length"] - QuantityVariable[Subscript["x", "i"], "Length"])](https://www.wolframcloud.com/objects/resourcesystem/marketplacestorage/resources/a79/a79c6b3c-7b5c-411c-a2c6-19b5fb21436c/Webpage/FormulaImage.png)
