Instructions:
  • Answer 16 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A simple machine that consists of a wheel over which a rope - chain - or wire passes






2. The work done by a machine; the product of the output force and the distance through which the force is exerted






3. The rate at which work is done or energy is transformed






4. The transfer of energy to an object by using a force that causes the object to move in the direction of the force






5. A device that helps do work by either overcoming a force or changing the direction of the applied force






6. A number that tells how many times a machine multiplies force.






7. Simple machine consisting of a bar free to pivot about a fixed point called the fulcrum.






8. A quantity - usually expressed as a percentage - that measures the ratio of work output to work input; it can be calculated by dividing work output by work input.






9. A simple machine consisting of two circular objects of different sizes; the wheel is the larger of the two circular objects






10. The unit used to express energy; equivalent to the amount of work done by a force of 1 N acting through a distance of 1 m in the direction of the force






11. The unit used to express power; equivalent to joules per second






12. A simple machine that is made up of two inclined planes and that moves; often used for cutting






13. A type of simple machine that consists of an inclined plane wrapped around a cylinder






14. A machine made of more than one simple machine






15. The work done on a machine; the product of the input force and the distance through which the force is exerted






16. A simple machine that is a straight - slanted surface - which facilitates the raising of loads; a ramp
