📚 Quick Study Guide

  • 📏 Definition: Uniform motion, also known as constant velocity, occurs when an object moves in a straight line at a constant speed. This means its velocity remains unchanged throughout the motion.
  • ⏱️ Key Characteristics:
    • ➡️ Constant Velocity: Both speed and direction remain the same.
    • 🛤️ Straight-Line Path: The object moves along a straight line.
    • Acceleration: The acceleration is zero.
  • Formulas:
    • 📏 Average Velocity: $v = \frac{\Delta x}{\Delta t}$, where $\Delta x$ is the displacement and $\Delta t$ is the time interval.
    • ⏱️ Displacement: $\Delta x = v \Delta t$
  • 💡 Important Notes:
    • ⚠️ Uniform motion is an idealization. In the real world, perfectly uniform motion is rare due to factors like friction and air resistance.
    • 📐 Vectors: Velocity is a vector quantity, so direction matters!
