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. Linear motion






2. Energy due to deformation






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






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






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






6. 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






7. Energy due to position






8. 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.






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






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






11. Accelerate our bodies






12. The capacity to do work






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






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






15. 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.






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






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






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






19. Rate of motion in a specific direction






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






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






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






23. Displacement/time






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






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






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






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






29. Rate of motion of an object






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






31. Mechanics of objects in accelerated motion.






32. The rate of doing work






33. 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.






34. Distance traveled/time






35. 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






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






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






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






39. Linear motion






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






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






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






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






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






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






46. Speed and velocity






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






48. Speeding up in a positive direction






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






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