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. Location in space in relation to a fix point






2. Rectilinear translation and Curvilinear translation






3. Accelerate our bodies






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






5. 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






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






7. Rate of motion in a specific direction






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






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






10. Linear motion






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






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






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






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






15. 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






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






17. Linear motion






18. Displacement/time






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






20. 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






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






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






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






24. The capacity to do work






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






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






27. 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.






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






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






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






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






32. 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.






33. Speeding up in a positive direction






34. Energy due to deformation






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






36. The muscle elongates is an example of negative work






37. Speed and velocity






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






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






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






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






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






43. Mechanics of objects in accelerated motion.






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






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






46. Energy due to motion






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






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






49. 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.






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