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. Location in space in relation to a fix point






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






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






4. Energy due to deformation






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






6. 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.






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






8. Linear motion






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






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






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






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






13. Displacement/time






14. 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.






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






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






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






18. Rectilinear translation and Curvilinear translation






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






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






21. The rate of doing work






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






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






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






26. Rate of motion in a specific direction






27. 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






28. Speed and velocity






29. Energy due to position






30. Mechanics of objects in accelerated motion.






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






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






33. The capacity to do work






34. 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






35. Speeding up in a positive direction






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






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






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






39. Energy due to motion






40. Linear motion






41. 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.






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






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






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






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






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






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






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






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






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