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






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






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






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






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






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






7. Mechanics of objects in accelerated motion.






8. 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






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






10. The branch of dynamics concerned with the forces that cause or tend to cause motion






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






12. Linear motion






13. Speeding up in a positive direction






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






15. The rate of doing work






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






17. Linear motion that occurs when a 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 - in strain lines






18. Speed and velocity






19. Displacement/time






20. The property of an object to resist changes in its motion.






21. Location in space in relation to a fix point






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






23. The science concerned with the effects of forces acting on objects.






24. 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.






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






26. Are forces that occur between objects in contact with each other i.e. air and water.






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






28. Energy due to position






29. The objects stay together and move with the same velocity after impact (full back and linebacker)






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






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






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






33. Accelerate our bodies






34. Linear motion






35. Rectilinear translation and Curvilinear translation






36. Energy due to deformation






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






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






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






40. 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.






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






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






43. The capacity to do work






44. Energy due to motion






45. Act perpendicular to the surface in contact and move the objects in opposite ways i.e. the downward force from a runners foot strike moves runner up away from the earth.






46. A measure of the length of a path followed by an object






47. When an object speeds up - slows down - starts - stops or changes direction. Can be positive or negative






48. The muscle elongates is an example of negative work






49. Distance traveled/time






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