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. Rate of motion of an object






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






3. Linear motion






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






5. Rectilinear translation and Curvilinear translation






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






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






8. The muscle elongates is an example of negative work






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






10. Location in space in relation to a fix point






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






12. Accelerate our bodies






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






14. Mechanics of objects in accelerated motion.






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






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






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






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






19. The capacity to do work






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. Energy due to position






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






23. Linear motion






24. Rate of motion in a specific direction






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






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






27. 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.






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






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






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






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






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






33. 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.






34. Speed and velocity






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






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






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






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






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






40. 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






41. Energy due to motion






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






43. 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.






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






45. Displacement/time






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






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






48. 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






49. The rate of doing work






50. Energy due to deformation
