  1. 3. The speed at which the acceleration of a falling object is zero because friction balances the weight.
  2. 5. A diagram showing all the forces acting on an object.
  3. 7. One if the pair of forces described in Newton’s third law.
  4. 8. The acceleration produced by a net forced on a body is directly proportional to the magnitude of the net force, is in the same direction as the net force, is inversely proportional to the mass of the body.
  5. 9. Force per unit of surface area where the forces is perpendicular to the surface; measure in pascals.
  6. 10. Anything that flows; in particular, any liquid or gas.

  1. 1. A mutual action between objects where each object exerts an equal and opposite force on the other.
  2. 2. When two values changes in opposite directions, so that if one increases the other decreases.
  3. 3. Terminal speed together with the direction of motion (down for falling objects.)
  4. 4. Friction, or drag, that acts on something moving through air.
  5. 6. The force that is equal in strength and opposite in directions to the action force, which acts simultaneously on whatever is exerting the action force.
  6. 8. Whenever one body exerts a force on a second body, the second body exerts an equal and opposite force on the first.
  7. 9. The SI unit pressure. One pascal (symbol Pa) of pressure exerts a normals forces of one newtons per square meter.
