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. 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.






2. 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






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






4. Displacement/time






5. 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






6. Speed and velocity






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






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






9. Distance traveled/time






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






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






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






13. Rate of motion in a specific direction






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






15. Accelerate our bodies






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






17. The muscle elongates is an example of negative work






18. Location in space in relation to a fix point






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






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






22. Speeding up in a positive direction






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






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






25. The rate of doing work






26. Mechanics of objects in accelerated motion.






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






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






29. Energy due to motion






30. 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






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






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






33. 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.






34. Rectilinear translation and Curvilinear translation






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






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






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






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






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






40. 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.






41. Rate of motion of an object






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






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






44. Energy due to position






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






46. Energy due to deformation






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






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






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






50. The capacity to do work
