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






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






3. 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.






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






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






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






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






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






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






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






11. Energy due to position






12. Energy due to motion






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






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. Linear motion






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






17. Distance traveled/time






18. Accelerate our bodies






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






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






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






22. Mechanics of objects in accelerated motion.






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






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






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






26. The rate of doing work






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






28. Location in space in relation to a fix point






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






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






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






32. 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






33. Speed and velocity






34. Rate of motion of an object






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






36. Energy due to deformation






37. Rate of motion in a specific direction






38. 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.






39. 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






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






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






42. Displacement/time






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






44. Rectilinear translation and Curvilinear translation






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






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






47. Speeding up in a positive direction






48. Linear motion






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






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