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






2. The capacity to do work






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






4. Rate of motion of an object






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






6. Energy due to position






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






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






9. Speed and velocity






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






11. Energy due to motion






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






13. 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.






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






15. Distance traveled/time






16. Accelerate our bodies






17. 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






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






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






20. Displacement/time






21. 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.






22. 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






23. Rate of motion in a specific direction






24. Location in space in relation to a fix point






25. Mechanics of objects in accelerated motion.






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






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






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






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






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






31. Speeding up in a positive direction






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






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






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






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






36. Energy due to deformation






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






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






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






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






41. The rate of doing work






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






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






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






45. The muscle elongates is an example of negative work






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






47. Rectilinear translation and Curvilinear translation






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






49. 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.






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