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 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






2. Speeding up in a positive direction






3. Mechanics of objects in accelerated motion.






4. Linear motion






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






6. 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.






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






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






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






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






11. Energy due to motion






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






13. Speed and velocity






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






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






16. Energy due to position






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






18. Rate of motion in a specific direction






19. Displacement/time






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






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






22. Accelerate our bodies






23. Rate of motion of an object






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






25. 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.






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






27. Distance traveled/time






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






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






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






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






32. 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.






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






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






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






36. 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






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






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






39. Linear motion






40. The capacity to do work






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






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






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






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






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






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






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






48. Rectilinear translation and Curvilinear translation






49. Energy due to deformation






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