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. Accelerate our bodies






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






3. 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.






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






5. The muscle elongates is an example of negative work






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






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






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






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






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






11. 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






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






13. The capacity to do work






14. Energy due to position






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






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






17. Linear motion






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






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






20. Location in space in relation to a fix point






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






22. 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.






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






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






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






26. Displacement/time






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






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






29. Mechanics of objects in accelerated motion.






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






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






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






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






34. 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.






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






37. Rectilinear translation and Curvilinear translation






38. Rate of motion in a specific direction






39. 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






40. Speed and velocity






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






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






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






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






45. Energy due to motion






46. Linear motion






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






48. Rate of motion of an object






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






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