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 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.






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






3. Rate of motion of an object






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






5. 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






6. 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






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






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






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






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






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






12. 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.






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






14. Distance traveled/time






15. Rate of motion in a specific direction






16. Linear motion






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






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






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






20. 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






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






22. The muscle elongates is an example of negative work






23. Accelerate our bodies






24. Energy due to deformation






25. 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.






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






27. Energy due to position






28. Rectilinear translation and Curvilinear translation






29. Displacement/time






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






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






32. Speeding up in a positive direction






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






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






35. Linear motion






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






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






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






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






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






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






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






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






44. Speed and velocity






45. 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.






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






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






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






49. Mechanics of objects in accelerated motion.






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