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 rate of doing work






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






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. Energy due to motion






5. The muscle elongates is an example of negative work






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






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






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






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






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






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






12. Linear motion






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






14. Location in space in relation to a fix point






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






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






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






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






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






20. Rate of motion in a specific direction






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






22. 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.






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






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






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






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






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






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






29. Accelerate our bodies






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






31. 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.






32. 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






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






34. Rate of motion of an object






35. Mechanics of objects in accelerated motion.






36. Rectilinear translation and Curvilinear translation






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






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






39. Energy due to position






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






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






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






43. Speeding up in a positive direction






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






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






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






48. 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.






49. Speed and velocity






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