Mechanical Principles Of Human Movement

Subject : engineering
Instructions:
  • Answer 50 questions in 30 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 branch of dynamics concerned with the forces that cause or tend to cause motion (external forces - Newton's laws).






2. 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.






3. Location in space in relation to a fix point






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






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






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






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






8. 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






9. Displacement/time






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






11. Speeding up in a positive direction






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






14. Speed and velocity






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






16. 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.






17. Linear motion






18. Energy due to deformation






19. Linear motion






20. The capacity to do work






21. Accelerate our bodies






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






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






24. Rate of motion of an object






25. 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






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






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






28. 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.






29. Rate of motion in a specific direction






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






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






32. The rate of doing work






33. Distance traveled/time






34. Rectilinear translation and Curvilinear translation






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






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






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






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






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






40. Energy due to position






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






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






43. 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






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






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






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






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






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






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






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