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






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






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






4. Energy due to position






5. 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.






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






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






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






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






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






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






12. Displacement/time






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






14. 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.






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






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






17. Mechanics of objects in accelerated motion.






18. The rate of doing work






19. Location in space in relation to a fix point






20. Linear motion






21. Linear motion






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






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






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






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






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






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






28. Distance traveled/time






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






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






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






32. 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.






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






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






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






36. The capacity to do work






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






38. 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






39. The muscle elongates is an example of negative work






40. 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.






41. Energy due to deformation






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






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






44. Rectilinear translation and Curvilinear translation






45. 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






46. The branch of dynamics concerned with the forces that cause or tend to cause motion (external forces - Newton's laws).






47. Speed and velocity






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






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






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