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






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






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






4. The capacity to do work






5. Linear motion






6. Accelerate our bodies






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






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






9. Speeding up in a positive direction






10. 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.






11. Mechanics of objects in accelerated motion.






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






13. The muscle elongates is an example of negative work






14. Location in space in relation to a fix point






15. Energy due to position






16. Rate of motion in a specific direction






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






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






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






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






21. Energy due to motion






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






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






24. 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.






25. 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






26. 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






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






28. Distance traveled/time






29. Displacement/time






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






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






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






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






34. 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.






35. Energy due to deformation






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






37. Linear motion






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






39. Rectilinear translation and Curvilinear translation






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






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






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






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






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






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






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






48. Rate of motion of an object






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






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