πŸ“š Quick Study Guide

  • πŸ“ Definition: Displacement is the shortest distance between an object's initial and final positions, including direction. It's a vector quantity.
  • 🧭 Vector vs. Scalar: Remember, displacement is a vector (magnitude and direction), unlike distance, which is a scalar (magnitude only).
  • πŸ“ Calculating Displacement: * In one dimension: $\Delta x = x_{f} - x_{i}$, where $x_{f}$ is the final position and $x_{i}$ is the initial position. * In two dimensions: Use vector components to find the resultant displacement.$\Delta r = \sqrt{(\Delta x)^2 + (\Delta y)^2}$
  • 🧭 Direction: The direction of displacement can be found using trigonometry (e.g., $\tan(\theta) = \frac{\Delta y}{\Delta x}$).
  • πŸ’‘ Key Points: * Displacement can be zero even if the distance traveled is not. * Displacement is independent of the path taken.
