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 science concerned with the effects of forces acting on objects.






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






3. 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.






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






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






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






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






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






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






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






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






12. The capacity to do work






13. Distance traveled/time






14. 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






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






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






17. Location in space in relation to a fix point






18. Accelerate our bodies






19. Rate of motion of an object






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






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






22. The muscle elongates is an example of negative work






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






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






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






26. Energy due to deformation






27. Rate of motion in a specific direction






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






29. 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.






30. 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






31. Energy due to motion






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






33. The rate of doing work






34. Speed and velocity






35. Mechanics of objects in accelerated motion.






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






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






38. Rectilinear translation and Curvilinear translation






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






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






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






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






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






44. 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






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. Speeding up in a positive direction






47. Energy due to position






48. Linear motion






49. Displacement/time






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