Mechanical Principles Of Human Movement

Subject : engineering
Instructions:
  • Answer 50 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 measure of the length of a path followed by an object






2. The means by which energy is transferred from one object or system to another






3. The capacity to do work






4. Everybody continues in a state of rest or of uniform motion in a straight line - unless it is compelled to change that state by forces impressed upon it






5. Act parallel to the contacts and opposes motion or sliding between the surfaces i.e. the backward of the runners foot strike gives the runner horizontal motion.






6. The shortening phase of the muscle in an isotonic lift is an example of positive work






7. Accelerate our bodies






8. The distance traveled in a straight line from the starting point to the ending point






9. To every action there is always opposed an equal reaction






10. The product of forece multiplied by the time that force acts






11. Measure of the force of gravity acting on an object. Changes with location.






12. Distance traveled/time






13. Occurs when an object moves in a positive direction but is slowing down






14. Location in space in relation to a fix point






15. Done by a force acting on an object when the object is displaced in the direction opposite the force acting on it






16. The branch of dynamics concerned with the description of motion (linear - angular and general motion).






17. The change of motion of an object is proportional to the force impressed; and is made in the direction of the straight line in which the force is impressed






18. Mechanics of objects at rest of moving at a constant velocity.






19. Change in position that occurs when all points on a body or object move in circular paths about the same fixed axis - also referred to as rotary motion or rotation.






20. In reference to height - the greater the height the more gravitational potential energy






21. Energy due to motion






22. Forces that act within the object or system whose motion is being investigated.






23. The study of forces and their effects on living systems.






24. All of the momentum of one object is transferred to the other (two pennies example)






25. Defined as the absolute value of the ratio of the velocity of separation of velocity of approach






26. Done by a force acting on an object if the object is displaced in the same direction as the force






27. A change in position that results from a combination of both linear and angular motion. Most movement is general is nature






28. Speed and velocity






29. Is a mathematical representation of anything that is defined by its size or magnitude (a number) and its direction (its orientation).






30. Linear motion that occurs when an object maintains its orientation during a movement so that all points on the object move the same distance - in the same direction - in the same time but not in straight lines.






31. Force that occur even if the objects are not touching i.e. gravity or magnetic.






32. Linear motion






33. The product of force and the amount of displacement in the direction of that force






34. Are forces that act on an object as a result of interaction with the environment surrounding it. Either non - contact or contact forces.






35. Speeding up in a positive direction






36. The action or process of change in position - in which two things are necessary.






37. Duration of an event - SI unit if seconds - minutes - hours and days all based on s.






38. Energy due to deformation






39. Linear motion






40. SI units are the most commonly accepted units of measure based on the metric system.






41. A push or a pull. They cause objects to start - stop - speed up - slow down or change direction. (N)






42. The rate of doing work






43. Used to describe a change in position - the SI unit is meters - may also see miles - yards - feet and inches.






44. Rate of motion in a specific direction






45. Rectilinear translation and Curvilinear translation






46. Energy due to position






47. Measure of inertia; the quantity of matter in an object. Does not change with location.






48. Displacement/time






49. The muscle elongates is an example of negative work






50. Mechanics of objects in accelerated motion.
