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






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






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






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






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






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






7. The rate of doing work






8. 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






9. Rate of motion of an object






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






11. Energy due to deformation






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






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






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






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






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






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






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






19. Linear motion






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






21. Speed and velocity






22. Linear motion






23. Location in space in relation to a fix point






24. Displacement/time






25. 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.






26. Rate of motion in a specific direction






27. 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.






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






29. The capacity to do work






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






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






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






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






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






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






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






37. Distance traveled/time






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






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






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






41. Mechanics of objects in accelerated motion.






42. Accelerate our bodies






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






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






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






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






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






48. Speeding up in a positive direction






49. 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






50. The muscle elongates is an example of negative work
