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






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






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






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






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






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






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






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






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






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






11. Displacement/time






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






13. Rectilinear translation and Curvilinear translation






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






15. Accelerate our bodies






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






17. Energy due to position






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






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






21. Location in space in relation to a fix point






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






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 science concerned with the effects of forces acting on objects.






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






26. Linear motion






27. Speeding up in a positive direction






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






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






30. Speed and velocity






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






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






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






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






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






36. Energy due to motion






37. Energy due to deformation






38. Mechanics of objects in accelerated motion.






39. The rate of doing work






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






41. Rate of motion of an object






42. 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.






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






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






45. Distance traveled/time






46. 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






47. 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.






48. Linear motion






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






50. 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.
