  1. 4. diagram A diagram that shows all the forces acting on a single object, used to analyze forces and predict motion.
  2. 7. The change in position of an object from its starting point, often measured in a straight line.
  3. 9. A group of interacting or interdependent parts that form a complex whole.
  4. 10. Second Law The law that states that the acceleration of an object depends on the mass of the object and the net force acting on it (F = ma).
  5. 12. First Law The law that states that an object at rest stays at rest, and an object in motion stays in motion, unless acted upon by an unbalanced force (also known as the law of inertia).
  6. 13. force The overall force acting on an object when all individual forces are combined.
  7. 16. The rate at which an object changes its velocity; can be caused by speeding up, slowing down, or changing direction.
  8. 17. The force exerted by gravity on an object's mass, typically measured in newtons (N).
  9. 18. force A force that keeps an object moving in a circular path, directed toward the center of the circle.
  10. 19. The tendency of an object to resist a change in its motion.

  1. 1. A push or pull exerted on an object that can cause it to accelerate, change direction, or stop.
  2. 2. Third Law The law that states that for every action, there is an equal and opposite reaction.
  3. 3. The product of an object's mass and velocity, indicating how much force is needed to stop it (momentum = mass × velocity).
  4. 5. To draw a conclusion based on evidence and reasoning.
  5. 6. The amount of matter in an object, which influences its resistance to acceleration.
  6. 8. forces Forces that are not equal, resulting in a change in an object's motion.
  7. 11. The speed of an object in a given direction.
  8. 14. forces Forces that are equal in size and opposite in direction, resulting in no change in an object's motion.
  9. 15. A force that opposes the motion of objects in contact, acting in the opposite direction of motion.
  10. 20. resistance A type of frictional force that acts against the motion of objects moving through the air.
