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. Rate of motion of an object






2. Energy due to position






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






4. Location in space in relation to a fix point






5. 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.






6. 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






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






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






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






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






11. Linear motion






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






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






14. The muscle elongates is an example of negative work






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






16. 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.






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






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






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






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






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






22. Rate of motion in a specific direction






23. Speed and velocity






24. 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






25. Accelerate our bodies






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






27. The capacity to do work






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






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






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






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






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






33. Energy due to motion






34. Energy due to deformation






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






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






37. Distance traveled/time






38. 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.






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






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






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






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






44. Speeding up in a positive direction






45. Rectilinear translation and Curvilinear translation






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






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






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






49. The rate of doing work






50. Linear motion
