Across
  1. 2. Velocity / An object's velocity is constant during a fall with zero acceleration.
  2. 4. Fall / objects that fall due to gravity alone with no other forces acting on them.
  3. 5. Forces / when a system touches another
  4. 9. / a contact force that opposes the movement of objects past each other.
  5. 10. / a push or pull on a system
  6. 12. acceleration / 9.81 meters per second
  7. 15. Force / A force that in combination with other forces acting on the same system produces a zero net force on the system.
  8. 18. equilibrium / the condition in which all forces acting on a system are balanced as indicated by the system's lack of acceleration.
  9. 19. Law of Motion / For every action there is an equal and opposite reaction.
Down
  1. 1. 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.
  2. 3. Force / is a force that acts on a system from the outside of the system's boundaries.
  3. 6. / states that objects continue moving until acted on by an external force.
  4. 7. Resistance / drag
  5. 8. / the unit measurement of force
  6. 10. 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.
  7. 11. force / if one force on a system is larger than the other.
  8. 13. / The mathematical description of such a spatial region
  9. 14. of Motion / The laws created by the English Physicist, Isaac Newton.
  10. 16. acceleration / when objects accelerate at a constant rate, as they do in free fall.
  11. 17. of Universal Gravitation / F = G \frac{m_1 m_2}{r^2}\
