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. Rate of motion of an object






2. Mechanics of objects in accelerated motion.






3. Rectilinear translation and Curvilinear translation






4. The muscle elongates is an example of negative work






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






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






7. 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.






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






9. Speeding up in a positive direction






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






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






12. Accelerate our bodies






13. The rate of doing work






14. 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






15. Energy due to motion






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






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






18. 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.






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






21. 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.






22. 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.






23. 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






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






25. Speed and velocity






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






27. Displacement/time






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






29. Location in space in relation to a fix point






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






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






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






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






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






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






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






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






38. Energy due to position






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






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






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






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






43. Energy due to deformation






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






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






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






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






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






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






50. Linear motion
