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






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






3. Rectilinear translation and Curvilinear translation






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






5. Linear motion






6. Rate of motion of an object






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






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






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






10. Speed and velocity






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






12. 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.






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






14. Accelerate our bodies






15. Energy due to deformation






16. Linear motion






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






18. The muscle elongates is an example of negative work






19. Location in space in relation to a fix point






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






21. Speeding up in a positive direction






22. Displacement/time






23. The capacity to do work






24. 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.






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






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






27. Energy due to position






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






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






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






31. Mechanics of objects in accelerated motion.






32. The rate of doing work






33. Energy due to motion






34. Distance traveled/time






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






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






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






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






39. 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.






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






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






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






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






44. Rate of motion in a specific direction






45. 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.






46. 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






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






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






49. 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






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