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






2. 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






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






4. Linear motion






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






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






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






8. 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






9. Speed and velocity






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






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






12. Location in space in relation to a fix point






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






14. The muscle elongates is an example of negative work






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






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






17. Accelerate our bodies






18. Displacement/time






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






20. Speeding up in a positive direction






21. Rectilinear translation and Curvilinear translation






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






23. The rate of doing work






24. Distance traveled/time






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






26. 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.






27. Linear motion






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






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






30. The capacity to do work






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






32. Energy due to deformation






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






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






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






36. Rate of motion in a specific direction






37. 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.






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






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






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






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






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






43. Energy due to position






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






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






46. Rate of motion of an object






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






48. 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.






49. Mechanics of objects in accelerated motion.






50. Energy due to motion
