Review Force and Motion-3

What is the difference between speed and velocity?

  1. Speed is faster.

    No. An object's speed is part of its velocity.
  2. Velocity has to be in a specific direction.

    Yes! An object's speed is measured in distance per time, such as 20 miles per hour. Its velocity must include a direction, such as north at 20 miles per hour.
  3. They mean the same thing.

    No. The two terms have different meanings.
  4. Speed is a general term and velocity is a scientific term.

    No. Both terms are used in science, and they mean different things.
