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. 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.






2. 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






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






4. 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.






5. Rate of motion of an object






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






7. The rate of doing work






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






9. Distance traveled/time






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






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






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






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






14. Location in space in relation to a fix point






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






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






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






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






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






20. Rate of motion in a specific direction






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






22. Linear motion






23. Energy due to motion






24. Mechanics of objects in accelerated motion.






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






26. 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






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






28. Speeding up in a positive direction






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






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






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






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






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






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






35. Accelerate our bodies






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






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






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






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






40. 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.






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






42. Displacement/time






43. Linear motion






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






45. Energy due to deformation






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






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






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






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






50. 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.
