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






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






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






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






5. 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.






6. The rate of doing work






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






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






9. The capacity to do work






10. Mechanics of objects in accelerated motion.






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






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






14. Energy due to motion






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






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






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






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






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






20. Rate of motion of an object






21. The muscle elongates is an example of negative work






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






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






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






25. Accelerate our bodies






26. Energy due to deformation






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






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






29. Displacement/time






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






31. Rate of motion in a specific direction






32. Speed and velocity






33. 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






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






35. Rectilinear translation and Curvilinear translation






36. 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






37. Distance traveled/time






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






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






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






41. Linear motion






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






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






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






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






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






47. Energy due to position






48. Location in space in relation to a fix point






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






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