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 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






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






3. Rate of motion of an object






4. Energy due to motion






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






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






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






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






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






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






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






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






13. Speed and velocity






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






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






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






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






18. Rectilinear translation and Curvilinear translation






19. Location in space in relation to a fix point






20. 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.






21. Rate of motion in a specific direction






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






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






24. Linear motion






25. The muscle elongates is an example of negative work






26. 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.






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






28. 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.






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






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






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






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






33. Distance traveled/time






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






35. The capacity to do work






36. Displacement/time






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






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






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






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






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






42. 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.






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






44. Accelerate our bodies






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






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






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






48. Energy due to deformation






49. 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






50. Mechanics of objects in accelerated motion.
