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






2. Energy due to position






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






4. 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.






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






6. Distance traveled/time






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






8. Rate of motion of an object






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






10. 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.






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






12. The muscle elongates is an example of negative work






13. Energy due to motion






14. Speeding up in a positive direction






15. 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.






16. Accelerate our bodies






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






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






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






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






21. The capacity to do work






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






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






24. Displacement/time






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






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






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






28. Linear motion






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






30. The rate of doing work






31. Energy due to deformation






32. 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






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






34. 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






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






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






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






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






39. Linear motion






40. Location in space in relation to a fix point






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






42. Rate of motion in a specific direction






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






44. 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






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






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






47. Speed and velocity






48. Mechanics of objects in accelerated motion.






49. Rectilinear translation and Curvilinear translation






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