Yes, speed can be zero but not negative. Speed is the magnitude of velocity and it represents how fast an object is moving. Zero speed means no movement. However, velocity can be negative if it indicates direction, such as moving backward.

FAQs & Answers

  1. Can speed ever be negative? No, speed is always zero or positive because it measures magnitude only and has no direction.
  2. What does zero speed mean? Zero speed means an object is not moving at all.
  3. How is velocity different from speed? Velocity includes both magnitude and direction, so it can be negative when indicating motion in the opposite direction.
