  1. 3. the resistance that one surface or object encounters when moving over another.
  2. 5. Force of attraction between two objects.
  3. 7. Forces are said to be "balanced" in their effects cancel each other and there is no change in the objects speed or direction.
  4. 9. a change in velocity over time passed, speed and direction make up velocity.

  1. 1. 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.
  2. 2. 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.
  3. 4. Velocity when an object in motion is moving in a strait line at a constant speed.
  4. 6. push or pull that caused an object to change speed, change direction, or to change shape or size, it is measured in Newtons (N).
  5. 8. mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied.
  6. 10. the resistance of an object to change in its speed or direction of its motion.
