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






2. The muscle elongates is an example of negative work






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






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






5. Rate of motion in a specific direction






6. Distance traveled/time






7. Energy due to motion






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






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






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






11. Linear motion






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






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






14. 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.






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






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






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






18. Displacement/time






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






20. Accelerate our bodies






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






22. 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.






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






24. Mechanics of objects in accelerated motion.






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






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






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






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






29. 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






30. 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.






31. 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






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






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






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






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






36. Speed and velocity






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






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






39. 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.






40. Energy due to deformation






41. Rate of motion of an object






42. Location in space in relation to a fix point






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






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






45. Linear motion






46. The rate of doing work






47. Energy due to position






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






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






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