Across
  1. 3. The total mechanical energy in an isolated system remains constant.
  2. 7. A force that has a component opposite to the direction of the displacement at the point of application of the force
  3. 8. The work done on an object by a net force is equal to the change in the object’s kinetic energy.
Down
  1. 1. The force has a component parallel to the displacement.
  2. 2. A force for which the work done in moving an object between two points depends on the path taken (frictional force, air resistance, tension).
  3. 4. A force for which the work done in moving an object between two points is independent of the path taken (gravitational force, elastic force, electrostatic force).
  4. 5. The product of force and displacement, with the force and the displacement in the same line.
  5. 6. The rate at which work is done or energy is expended.
