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. Energy due to motion






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






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






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






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






6. The muscle elongates is an example of negative work






7. 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.






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






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






10. The rate of doing work






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






12. Distance traveled/time






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






14. Speeding up in a positive direction






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






16. Energy due to deformation






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






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






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






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






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






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






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






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






25. 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






26. Speed and velocity






27. The capacity to do work






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






29. Linear motion






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






31. Rate of motion of an object






32. Rectilinear translation and Curvilinear translation






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






34. Rate of motion in a specific direction






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






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






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






38. Energy due to position






39. Displacement/time






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






41. 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.






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






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






44. 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.






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






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






47. 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






48. 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






49. Linear motion






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