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






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






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






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






5. Rectilinear translation and Curvilinear translation






6. Accelerate our bodies






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






8. The rate of doing work






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






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






11. 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.






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






13. Energy due to position






14. 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






15. 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.






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






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






18. Speed and velocity






19. The muscle elongates is an example of negative work






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






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






22. 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






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






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






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






26. Rate of motion of an object






27. Linear motion






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






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






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






31. Linear motion






32. Distance traveled/time






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






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






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






36. 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.






37. 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






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






39. Speeding up in a positive direction






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






41. Energy due to deformation






42. Energy due to motion






43. The capacity to do work






44. Location in space in relation to a fix point






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






46. Displacement/time






47. 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.






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






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






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