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. Speeding up in a positive direction






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






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






4. Mechanics of objects in accelerated motion.






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






6. Energy due to position






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






8. Energy due to motion






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






10. Speed and velocity






11. 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.






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






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






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






15. Displacement/time






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






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






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






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






20. Distance traveled/time






21. Energy due to deformation






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






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






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






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






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






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






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






29. Rate of motion in a specific direction






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






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






32. Rectilinear translation and Curvilinear translation






33. Rate of motion of an object






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






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






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






37. Linear motion






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






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






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






41. The muscle elongates is an example of negative work






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






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






44. The capacity to do work






45. 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






46. 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.






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






48. 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.






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






50. 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
