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






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






3. Location in space in relation to a fix point






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






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






6. Mechanics of objects in accelerated motion.






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






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






9. The rate of doing work






10. 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






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






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






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






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






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






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






17. Accelerate our bodies






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






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 product of force and the amount of displacement in the direction of that force






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






22. 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






23. 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






24. Distance traveled/time






25. Rectilinear translation and Curvilinear translation






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






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






28. The muscle elongates is an example of negative work






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






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






31. Rate of motion of an object






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






33. 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.






34. Linear motion






35. Speeding up in a positive direction






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






37. Energy due to motion






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






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






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






41. Rate of motion in a specific direction






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






43. Displacement/time






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






45. 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.






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






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






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






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






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