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






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






3. Mechanics of objects in accelerated motion.






4. Linear motion






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






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






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






8. The capacity to do work






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






10. Energy due to motion






11. Speed and velocity






12. The muscle elongates is an example of negative work






13. Distance traveled/time






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






15. Location in space in relation to a fix point






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






17. The rate of doing work






18. 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.






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






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






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






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






23. Rectilinear translation and Curvilinear translation






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






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






26. Linear motion






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






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






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






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






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






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






33. Speeding up in a positive direction






34. Energy due to position






35. Rate of motion of an object






36. Energy due to deformation






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






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






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






40. 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.






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






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






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






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






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






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






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






48. Displacement/time






49. Rate of motion in a specific direction






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