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






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






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






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






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






7. Energy due to position






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






9. 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.






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






11. Linear motion






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






13. Accelerate our bodies






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






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






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






17. The capacity to do work






18. 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.






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






20. 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.






21. 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






22. 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






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






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






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






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






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






28. 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.






29. Rate of motion in a specific direction






30. Location in space in relation to a fix point






31. Linear motion






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






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






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






35. Rate of motion of an object






36. The muscle elongates is an example of negative work






37. Energy due to motion






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






39. Energy due to deformation






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






41. Speed and velocity






42. Distance traveled/time






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






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






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






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






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






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






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






50. Rectilinear translation and Curvilinear translation
