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






2. Speeding up in a positive direction






3. 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.






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






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






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






7. 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






8. The capacity to do work






9. Linear motion






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






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






12. The rate of doing work






13. The muscle elongates is an example of negative work






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






15. Rate of motion of an object






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






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






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






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






20. Rate of motion in a specific direction






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






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






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






24. Location in space in relation to a fix point






25. 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






26. 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






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






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






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






30. 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.






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






32. Linear motion






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






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






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






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






37. 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.






38. Energy due to position






39. Energy due to motion






40. Accelerate our bodies






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






42. Mechanics of objects in accelerated motion.






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






44. 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.






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






46. Distance traveled/time






47. Speed and velocity






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






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






50. Displacement/time
