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 product of forece multiplied by the time that force acts






2. 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






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






4. The muscle elongates is an example of negative work






5. 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.






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






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






9. Rectilinear translation and Curvilinear translation






10. Speeding up in a positive direction






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






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






13. Mechanics of objects in accelerated motion.






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






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






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






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






18. Speed and velocity






19. Rate of motion in a specific direction






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






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






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






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






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






25. Energy due to position






26. 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.






27. Linear motion






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






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






30. Accelerate our bodies






31. 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.






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






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






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






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






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






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






38. Rate of motion of an object






39. Energy due to deformation






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






41. 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.






42. Linear motion






43. Energy due to motion






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






45. The capacity to do work






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






47. Distance traveled/time






48. Location in space in relation to a fix point






49. 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






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