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 position






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






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






4. 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






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






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






7. The capacity to do work






8. Location in space in relation to a fix point






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






10. Speeding up in a positive direction






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






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






13. The rate of doing work






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






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






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






17. Energy due to motion






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






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






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






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






22. Rectilinear translation and Curvilinear translation






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






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






25. Energy due to deformation






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






27. 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






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






29. Linear motion






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






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






32. Accelerate our bodies






33. Distance traveled/time






34. Mechanics of objects in accelerated motion.






35. 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.






36. 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.






37. 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.






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






39. Speed and velocity






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






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






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






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






44. Rate of motion of an object






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






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






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






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






49. 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.






50. Displacement/time
