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. Rectilinear translation and Curvilinear translation






2. Speed and velocity






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






4. 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.






5. 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.






6. Mechanics of objects in accelerated motion.






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






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






9. Distance traveled/time






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






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






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






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






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






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






16. Energy due to position






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






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






19. Rate of motion in a specific direction






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






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






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






23. The muscle elongates is an example of negative work






24. 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






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






26. The rate of doing work






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






28. The capacity to do work






29. Accelerate our bodies






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






31. Linear motion






32. Energy due to motion






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






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






35. Speeding up in a positive direction






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






37. Displacement/time






38. 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.






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






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






41. 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.






42. Energy due to deformation






43. 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






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






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






46. 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






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






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






49. Linear motion






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