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. 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






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






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






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






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






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






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






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






13. Distance traveled/time






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






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






16. Location in space in relation to a fix point






17. Speeding up in a positive direction






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






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






20. The muscle elongates is an example of negative work






21. Rate of motion of an object






22. Speed and velocity






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






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






25. The rate of doing work






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






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






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






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






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






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






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






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






34. Energy due to motion






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






36. Energy due to position






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






38. 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.






39. Mechanics of objects in accelerated motion.






40. Accelerate our bodies






41. The capacity to do work






42. Linear motion






43. Energy due to deformation






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






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






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






47. Displacement/time






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






49. 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.






50. Rectilinear translation and Curvilinear translation
