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 in accelerated motion.






2. The rate of doing work






3. Distance traveled/time






4. Energy due to motion






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






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






8. 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






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






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






11. Energy due to deformation






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






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






14. Rate of motion of an object






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






16. Accelerate our bodies






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






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






19. 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.






20. Energy due to position






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






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






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






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






25. 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






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






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






28. The capacity to do work






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






30. 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.






31. Displacement/time






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






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






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






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






36. Location in space in relation to a fix point






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






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






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






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






42. The muscle elongates is an example of negative work






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






44. Linear motion






45. Linear motion






46. Rectilinear translation and Curvilinear translation






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






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






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






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