  1. 3. Velocity: when an object in motion is moving in a strait line at a constant speed.
  2. 5. the resistance of an object to change in its speed or direction of its motion.
  3. 7. first law of motion: an object at rest will remain at rest, and an object in motion will remain at a constant velocity unless acted on by an unbalanced force.
  4. 8. mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied.
  5. 9. a change in velocity over time passed, speed and direction make up velocity.
  6. 10. Force of attraction between two objects.
Down
  1. 1. the resistance that one surface or object encounters when moving over another.
  2. 2. push or pull that caused an object to change speed, change direction, or to change shape or size, it is measured in Newtons (N).
  3. 4. Forces are said to be "balanced" in their effects cancel each other and there is no change in the objects speed or direction.
  4. 6. Forces are said to be "unbalanced" in their effects do not cancel each other and there is a change in the objects speed or direction.
