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 product of forece multiplied by the time that force acts






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






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






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






5. Speed and velocity






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






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






8. Energy due to motion






9. Rate of motion of an object






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






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






12. 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.






13. 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






14. Displacement/time






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






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






17. Speeding up in a positive direction






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






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






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






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






22. The capacity to do work






23. The muscle elongates is an example of negative work






24. Rectilinear translation and Curvilinear translation






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






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






27. Energy due to position






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






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






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






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






32. 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.






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






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






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






36. Mechanics of objects in accelerated motion.






37. Linear motion






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






39. Accelerate our bodies






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






41. 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






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






43. 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.






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






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






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






48. Location in space in relation to a fix point






49. Energy due to deformation






50. Linear motion
