Across
  1. 3. a unit of force that will accelerate one kilogram of mass one meter per second squared
  2. 6. a set of forces acting on an object that do not cancel each other out, resulting in a non-zero net force
  3. 10. How fast an object is speeding up
  4. 13. the force that prevents two stationary surfaces in contact from sliding relative to each other
  5. 14. the universal force of attraction between any two objects with mass or energy
  6. 15. How heavy an object is
Down
  1. 1. two or more forces acting on an object that are equal in magnitude (strength) and opposite in direction, resulting in a net force of zero
  2. 2. a resistive force that opposes the motion of a body rolling across a surface, such as a ball or wheel
  3. 4. tendency of an object to resist any change in its state of motion, whether it's at rest or moving at a constant velocity
  4. 5. "amount of stuff" in an object
  5. 7. the resistive force exerted by a fluid (like a liquid or gas) on an object moving through it or between layers of the fluid itself
  6. 8. the force that opposes the relative motion between two surfaces sliding against each other
  7. 9. an interaction that, when unopposed, causes a change in an object's motion by changing its speed, direction, or both
  8. 11. a vector quantity that measures the "quantity of motion" an object possesses, calculated as the product of its mass and velocity
  9. 12. the total force acting on an object, calculated as the vector sum of all individual forces
