Vector quantities are physical quantities that have both magnitude and direction. Examples include velocity, force, and acceleration. For instance, if a car is moving at 60 kilometers per hour to the north, its speed (60 km/h) is the magnitude, while the direction (north) is essential to fully describe its motion. In contrast to scalar quantities, which only have magnitude (like temperature or mass), vector quantities provide more information. This makes them crucial in physics and engineering, where understanding the direction of forces or movements is necessary for accurate calculations and predictions.
