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 muscle elongates is an example of negative work






2. Mechanics of objects in accelerated motion.






3. 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






4. Energy due to deformation






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






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






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






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






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






10. Rate of motion of an object






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






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






13. Accelerate our bodies






14. 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.






15. Speeding up in a positive direction






16. The capacity to do work






17. Energy due to motion






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






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






20. 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.






21. Rectilinear translation and Curvilinear translation






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






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






24. Linear motion






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






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






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






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






29. Energy due to position






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






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






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






33. 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






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






35. Location in space in relation to a fix point






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






37. 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.






38. Rate of motion in a specific direction






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






40. Linear motion






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






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






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






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






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. Distance traveled/time






47. The rate of doing work






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






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