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 property of an object to resist changes in its motion.






2. Distance traveled/time






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






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






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






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






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






10. Linear motion






11. The rate of doing work






12. Energy due to position






13. Mechanics of objects in accelerated motion.






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






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






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






17. Energy due to motion






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






19. Speed and velocity






20. 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.






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






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






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






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






26. The capacity to do work






27. Energy due to deformation






28. Speeding up in a positive direction






29. The muscle elongates is an example of negative work






30. Accelerate our bodies






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






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






33. 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.






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






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






36. 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.






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






38. Rectilinear translation and Curvilinear translation






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






40. Rate of motion of an object






41. 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.






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






43. Linear motion






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






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






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






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






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






49. Rate of motion in a specific direction






50. 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
