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 property of an object to resist changes in its motion.






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






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






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






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






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






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






8. Linear motion






9. Energy due to deformation






10. Accelerate our bodies






11. Displacement/time






12. 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






13. Energy due to position






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






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






16. 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.






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






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






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






20. The rate of doing work






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






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






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






24. Speed and velocity






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






26. Rectilinear translation and Curvilinear translation






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






28. Rate of motion of an object






29. Distance traveled/time






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






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






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






33. 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.






34. 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






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






36. Energy due to motion






37. Speeding up in a positive direction






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






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






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






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






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






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






45. 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.






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






47. Mechanics of objects in accelerated motion.






48. The muscle elongates is an example of negative work






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






50. Rate of motion in a specific direction
