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. Accelerate our bodies






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






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






4. 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.






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






6. Speeding up in a positive direction






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






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. Energy due to deformation






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






11. 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.






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. Rate of motion of an object






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






15. Linear motion






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






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






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






19. The capacity to do work






20. 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






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






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






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






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






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






26. Speed and velocity






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






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






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






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






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






33. Distance traveled/time






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






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






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






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






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






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






40. Displacement/time






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






42. Mechanics of objects in accelerated motion.






43. Rectilinear translation and Curvilinear translation






44. Rate of motion in a specific direction






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






46. Energy due to position






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






48. The rate of doing work






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






50. 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.
