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. Speeding up in a positive direction






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






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






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






5. Mechanics of objects in accelerated motion.






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






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






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






9. Rate of motion in a specific direction






10. Distance traveled/time






11. 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.






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






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






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






15. 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






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






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






18. Energy due to motion






19. Speed and velocity






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






21. 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.






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






23. Location in space in relation to a fix point






24. Linear motion






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






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






27. Displacement/time






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






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






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






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






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






33. The muscle elongates is an example of negative work






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






35. Rate of motion of an object






36. Energy due to position






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






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






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






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






41. The capacity to do work






42. 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






43. Linear motion






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






45. Energy due to deformation






46. Accelerate our bodies






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






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






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