📚 Quick Study Guide

  • 🚗 Motion: The act or process of moving or being moved.
  • ⏱️ Speed: The rate at which someone or something moves ($speed = \frac{distance}{time}$). Measured in meters per second (m/s) or kilometers per hour (km/h).
  • 🧭 Direction: The course or path along which something is moving or pointing (e.g., North, South, East, West).
  • ➡️ Velocity: Speed with a direction. It's a vector quantity.
  • ⚖️ Acceleration: The rate of change of velocity ($acceleration = \frac{change \ in \ velocity}{time}$). Measured in meters per second squared (m/s²).
  • 💡 Displacement: The change in position of an object.
  • 📐 Vectors: Quantities that have both magnitude and direction (e.g., velocity, acceleration, force).
