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






2. 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






3. The rate of doing work






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






5. 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






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






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






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






9. Distance traveled/time






10. Rectilinear translation and Curvilinear translation






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






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






13. Energy due to motion






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






15. Linear motion






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






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






18. 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.






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






20. Energy due to position






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






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






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






24. Displacement/time






25. Rate of motion of an object






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






27. Speeding up in a positive direction






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






29. Speed and velocity






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






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






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






33. Rate of motion in a specific direction






34. 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.






35. Accelerate our bodies






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






37. Energy due to deformation






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






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






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






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






42. The capacity to do work






43. Location in space in relation to a fix point






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






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. Linear motion






47. The muscle elongates is an example of negative work






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






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






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