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 study of forces and their effects on living systems.






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






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






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






5. 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






6. Linear motion






7. Energy due to position






8. 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.






9. Linear motion






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






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






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






13. Accelerate our bodies






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






15. The capacity to do work






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






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






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






19. 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.






20. Displacement/time






21. Energy due to motion






22. Speed and velocity






23. Rectilinear translation and Curvilinear translation






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






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






26. Distance traveled/time






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






28. Location in space in relation to a fix point






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






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






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






32. 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.






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






34. 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.






35. The rate of doing work






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






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






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






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






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






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






42. Speeding up in a positive direction






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






44. Energy due to deformation






45. Rate of motion of an object






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






47. Mechanics of objects in accelerated motion.






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






49. The muscle elongates is an example of negative work






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