45 views

The scientific name for speed is 'velocity.' In physics, velocity is defined as the rate at which an object changes its position, and it is a vector quantity, meaning it has both magnitude and direction.

FAQs & Answers

  1. What is the difference between speed and velocity? Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes both speed and direction.
  2. Why is velocity considered a vector quantity? Velocity includes both magnitude and direction, which means it specifies the rate of change of position and the direction in which the object is moving.
  3. How is velocity measured in physics? Velocity is measured by dividing the displacement of an object by the time taken, considering the direction of motion.
