  1. 1. Velocity An object's velocity is constant during a fall with zero acceleration.
  2. 4. the unit measurement of force
  3. 6. Fall objects that fall due to gravity alone with no other forces acting on them.
  4. 9. acceleration when objects accelerate at a constant rate, as they do in free fall.
  5. 10. acceleration 9.81 meters per second
  6. 11. Force A force that in combination with other forces acting on the same system produces a zero net force on the system.
  7. 14. a contact force that opposes the movement of objects past each other.
  8. 16. equilibrium the condition in which all forces acting on a system are balanced as indicated by the system's lack of acceleration.
  9. 19. The mathematical description of such a spatial region

  1. 2. Force is a force that acts on a system from the outside of the system's boundaries.
  2. 3. Law of Motion For every action there is an equal and opposite reaction.
  3. 5. Forces when a system touches another
  4. 6. a push or pull on a system
  5. 7. Resistance drag
  6. 8. force if one force on a system is larger than the other.
  7. 12. Law of Motion Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
  8. 13. Law of Motion The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
  9. 15. of Universal Gravitation F = G \frac{m_1 m_2}{r^2}\
  10. 17. states that objects continue moving until acted on by an external force.
  11. 18. of Motion The laws created by the English Physicist, Isaac Newton.
