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. 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.






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






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






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






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






6. Accelerate our bodies






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






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






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






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






11. Location in space in relation to a fix point






12. Linear motion






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






14. Linear motion






15. 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






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






17. Mechanics of objects in accelerated motion.






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






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






20. 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






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






22. Speed and velocity






23. Displacement/time






24. The capacity to do work






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






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






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






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






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






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






31. Rate of motion of an object






32. Energy due to deformation






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






34. The rate of doing work






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






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






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






38. The muscle elongates is an example of negative work






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






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






41. Energy due to position






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






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






44. Distance traveled/time






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






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






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






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






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






50. Rate of motion in a specific direction
