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. 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.






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






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






4. Speeding up in a positive direction






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






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






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






8. Mechanics of objects in accelerated motion.






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






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






11. Energy due to motion






12. Linear motion






13. Energy due to position






14. The muscle elongates is an example of negative work






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






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






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






18. Rate of motion in a specific direction






19. Location in space in relation to a fix point






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






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






22. Distance traveled/time






23. 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






24. 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






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






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






27. The rate of doing work






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






29. Linear motion






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






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






32. Rectilinear translation and Curvilinear translation






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






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






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






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. Speed and velocity






38. 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.






39. The capacity to do work






40. 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






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






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






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






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






45. Displacement/time






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






47. Accelerate our bodies






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






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






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