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






2. The rate of doing work






3. Energy due to deformation






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






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






6. Rate of motion in a specific direction






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






8. Rectilinear translation and Curvilinear translation






9. Linear motion






10. 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.






11. Location in space in relation to a fix point






12. 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






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






14. Linear motion






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






16. Displacement/time






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






18. Speeding up in a positive direction






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






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






21. Speed and velocity






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






23. Distance traveled/time






24. The muscle elongates is an example of negative work






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






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






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






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






29. 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






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






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






32. Rate of motion of an object






33. 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.






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






35. 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.






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






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






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






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






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






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






42. Mechanics of objects in accelerated motion.






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






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






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






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






47. Energy due to position






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






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






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