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






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






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






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






5. Linear motion






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






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






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






9. Rectilinear translation and Curvilinear translation






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






11. Accelerate our bodies






12. 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.






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






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






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






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






17. The capacity to do work






18. Rate of motion in a specific direction






19. Rate of motion of an object






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






21. 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






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






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






24. Linear motion






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






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






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






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






29. 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






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






31. 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.






32. The rate of doing work






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






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






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






36. Distance traveled/time






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






38. Speed and velocity






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






40. Mechanics of objects in accelerated motion.






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






42. The muscle elongates is an example of negative work






43. 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






44. Location in space in relation to a fix point






45. Energy due to deformation






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






47. Energy due to motion






48. Energy due to position






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






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