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. 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.






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






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






4. Distance traveled/time






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






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






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






8. Accelerate our bodies






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






10. Mechanics of objects in accelerated motion.






11. Location in space in relation to a fix point






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






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






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






15. Linear motion






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






17. 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.






18. 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.






19. Rate of motion in a specific direction






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






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






22. The rate of doing work






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






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






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






26. Displacement/time






27. Energy due to position






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






29. Rate of motion of an object






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






31. Linear motion






32. Speeding up in a positive direction






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






34. 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






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






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






37. The capacity to do work






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






39. Rectilinear translation and Curvilinear translation






40. 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






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






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






43. Speed and velocity






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






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






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






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






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






49. 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.






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