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






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






3. Energy due to motion






4. The rate of doing work






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






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






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






8. 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






9. Displacement/time






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






11. 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.






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






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






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






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






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






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






18. Rate of motion of an object






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






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






21. The muscle elongates is an example of negative work






22. Rectilinear translation and Curvilinear translation






23. Energy due to deformation






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






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






26. Location in space in relation to a fix point






27. 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.






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






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






30. Speed and velocity






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






32. Rate of motion in a specific direction






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






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






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






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






37. Linear motion






38. Mechanics of objects in accelerated motion.






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






40. 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






41. Speeding up in a positive direction






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






43. Distance traveled/time






44. Accelerate our bodies






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






46. The capacity to do work






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






48. Linear motion






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






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