  1. 3. The SI unit of force, defined as the force needed to accelerate a one-kilogram mass at a rate of one meter per second squared (1m/s^2)
  2. 9. The total, resultant force acting on an object, calculated by adding all individual forces as vectors
  3. 10. The rate at which velocity changes over time
  4. 13. The average location of all the mass in a system, acting as a single point where an object's entire mass is concentrated for analytical purposes
  5. 15. A force that opposes relative motion between surfaces in contact
  6. 16. A measure of the amount of matter in an object and its inertia, which is its resistance to acceleration
Down
  1. 1. An interaction that causes a change in an object's motion, shape, or velocity
  2. 2. A region of space where an object would experience a non-contact force, with the field's strength and direction at each point described by vectors
  3. 4. The force exerted on an object due to gravity
  4. 5. The tendency of an object to resist changes in its state of motion
  5. 6. A visual representation of all the external forces acting on a single object in a physics problem
  6. 7. The contact force exerted by a surface on an object that is perpendicular to the surface
  7. 8. A quantity that has both magnitude (size or length) and direction
  8. 11. A state where an object is not accelerating because the net force and net torque acting on it are both zero
  9. 12. The single force, velocity, or other vector quantity that has the same effect as two or more other vectors acting on an object
  10. 14. A scalar quantity that defines the rate at which an object covers distance
