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. Rate of motion of an object






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






3. Location in space in relation to a fix point






4. The muscle elongates is an example of negative work






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






6. Accelerate our bodies






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






8. Energy due to motion






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






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






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






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






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






14. Rate of motion in a specific direction






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






16. Distance traveled/time






17. Rectilinear translation and Curvilinear translation






18. Speed and velocity






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






20. Energy due to position






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






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






23. The rate of doing work






24. 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.






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






26. 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.






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






28. Linear motion






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






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






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






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






33. 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.






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






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






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






37. Linear motion






38. 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






39. 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.






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






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






42. Displacement/time






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






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






45. The capacity to do work






46. Speeding up in a positive direction






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






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






49. Energy due to deformation






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