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






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






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






4. Energy due to motion






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






6. Displacement/time






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






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






9. Rate of motion in a specific direction






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






11. The rate of doing work






12. The muscle elongates is an example of negative work






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






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






15. Speeding up in a positive direction






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






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






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






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






20. Location in space in relation to a fix point






21. 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.






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






23. Linear motion






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






25. 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






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






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






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






29. Energy due to position






30. Mechanics of objects in accelerated motion.






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






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






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






34. Energy due to deformation






35. Rate of motion of an object






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






37. 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.






38. The capacity to do work






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






40. Linear motion






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






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






43. Accelerate our bodies






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






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






46. 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.






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






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






50. Speed and velocity
