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 in a specific direction






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






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






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






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






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






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






8. Displacement/time






9. Linear motion






10. Location in space in relation to a fix point






11. 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.






12. Mechanics of objects in accelerated motion.






13. Rate of motion of an object






14. Energy due to deformation






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






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






17. Energy due to position






18. Energy due to motion






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






20. 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






21. 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






22. 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.






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






24. Speed and velocity






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






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






27. Rectilinear translation and Curvilinear translation






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






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






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






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






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






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






34. Distance traveled/time






35. The muscle elongates is an example of negative work






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






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






38. 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






39. The rate of doing work






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






41. Speeding up in a positive direction






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






43. Accelerate our bodies






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






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






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






47. The capacity to do work






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






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






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