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 study of forces and their effects on living systems.






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






3. Location in space in relation to a fix point






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






5. Linear motion






6. Speed and velocity






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






8. 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.






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






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






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






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






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






14. 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.






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






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






17. Rate of motion in a specific direction






18. The rate of doing work






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






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






21. The capacity to do work






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






23. Rectilinear translation and Curvilinear translation






24. Energy due to deformation






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






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






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






28. Energy due to motion






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






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






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






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






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






34. Linear motion






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






36. 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






37. Mechanics of objects in accelerated motion.






38. Speeding up in a positive direction






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






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






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






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






43. Accelerate our bodies






44. 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.






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






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






47. Displacement/time






48. The muscle elongates is an example of negative work






49. Rate of motion of an object






50. 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
