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. Rectilinear translation and Curvilinear translation






2. Speeding up in a positive direction






3. Rate of motion of an object






4. The capacity to do work






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






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






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






8. 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.






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






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






11. Linear motion






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






13. Accelerate our bodies






14. 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.






15. Location in space in relation to a fix point






16. 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






17. The rate of doing work






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






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






20. 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.






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






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






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






24. Energy due to position






25. Mechanics of objects in accelerated motion.






26. Linear motion






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






28. 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.






29. Energy due to motion






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






31. Displacement/time






32. The muscle elongates is an example of negative work






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






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






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






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






37. Speed and velocity






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






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






40. Energy due to deformation






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






42. Distance traveled/time






43. 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






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






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






46. 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






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






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






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






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