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






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






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






4. Energy due to motion






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






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






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






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






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






10. 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.






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






12. Mechanics of objects in accelerated motion.






13. Location in space in relation to a fix point






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






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






16. Rate of motion of an object






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






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






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






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






21. Rate of motion in a specific direction






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






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






24. Speeding up in a positive direction






25. 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.






26. Accelerate our bodies






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. The muscle elongates is an example of negative work






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






31. Speed and velocity






32. 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.






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






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






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






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






37. Linear motion






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






39. Energy due to deformation






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






41. 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






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






43. The rate of doing work






44. Linear motion






45. Rectilinear translation and Curvilinear translation






46. The capacity to do work






47. 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






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






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






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