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






2. The rate of doing work






3. 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






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






5. Speeding up in a positive direction






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






7. 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.






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






9. Linear motion






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






11. Mechanics of objects in accelerated motion.






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






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






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






15. Energy due to position






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






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






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






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






20. Rate of motion of an object






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






22. 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






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






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






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






26. Energy due to motion






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






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






29. Displacement/time






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






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






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






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






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






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






36. Speed and velocity






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






38. Accelerate our bodies






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






40. The capacity to do work






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






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






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






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






45. 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.






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






47. 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.






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






49. 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.






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