ASVAB Mechanical Comprehension Energy, Work, & Power Practice Test 18292
Work
Work is accomplished when force is applied to an object: W = Fd where F is force in newtons (N) and d is distance in meters (m). Thus, the more force that must be applied to move an object, the more work is done and the farther an object is moved by exerting force, the more work is done.
If the green arrow in this diagram represents 160 ft⋅lb of work, how far will the box move if it weighs 80 pounds?
| 160 ft. | |
| 2 ft. | |
