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. Displacement/time






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






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






4. Location in space in relation to a fix point






5. 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.






6. Accelerate our bodies






7. Distance traveled/time






8. Linear motion






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






10. Speeding up in a positive direction






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






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






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






14. 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.






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






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






17. 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.






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






19. Rate of motion of an object






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






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






22. Energy due to position






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






24. Mechanics of objects in accelerated motion.






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






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






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






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






29. Energy due to motion






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






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






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






33. 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






34. Energy due to deformation






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






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






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






38. 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






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






40. The rate of doing work






41. Rectilinear translation and Curvilinear translation






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






43. Linear motion






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






45. 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.






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






48. Speed and velocity






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






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