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. 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.






2. Displacement/time






3. 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.






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






5. Rate of motion of an object






6. Speed and velocity






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






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






9. 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.






10. 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






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






12. The muscle elongates is an example of negative work






13. Accelerate our bodies






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






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






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






17. Speeding up in a positive direction






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






19. The rate of doing work






20. Energy due to position






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






22. Rectilinear translation and Curvilinear translation






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






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






25. Linear motion






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






27. Mechanics of objects in accelerated motion.






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






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






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






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






32. 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.






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






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






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






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






37. Rate of motion in a specific direction






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






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






40. Energy due to deformation






41. Location in space in relation to a fix point






42. 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






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






44. Linear motion






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






46. Energy due to motion






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






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






49. 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






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