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. Speeding up in a positive direction






2. 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.






3. Accelerate our bodies






4. Energy due to position






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






6. Location in space in relation to a fix point






7. The capacity to do work






8. Speed and velocity






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






10. Rectilinear translation and Curvilinear translation






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






12. 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.






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






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






15. 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






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






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






18. Energy due to deformation






19. Displacement/time






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






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






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






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






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






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






26. Rate of motion in a specific direction






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






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






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






30. The rate of doing work






31. 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






32. Distance traveled/time






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






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






35. Rate of motion of an object






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






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






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






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






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






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






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






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






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






45. Mechanics of objects in accelerated motion.






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






47. Linear motion






48. 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.






49. Energy due to motion






50. The muscle elongates is an example of negative work
