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. To every action there is always opposed an equal reaction






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






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






5. Linear motion






6. Accelerate our bodies






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 description of motion (linear - angular and general motion).






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






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






11. The muscle elongates is an example of negative work






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






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






14. Speed and velocity






15. Rate of motion of an object






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






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






18. The rate of doing work






19. 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.






20. Rate of motion in a specific direction






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






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






23. Displacement/time






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






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






26. Speeding up in a positive direction






27. Everybody continues in a state of rest or of uniform motion in a straight line - unless it is compelled to change that state by forces impressed upon it






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






29. Energy due to position






30. Linear motion






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






32. 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.






33. 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.






34. Rectilinear translation and Curvilinear translation






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






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






37. 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






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






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






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






41. Energy due to deformation






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






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






44. 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






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






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






47. Energy due to motion






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






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






50. The capacity to do work
