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






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






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






4. Accelerate our bodies






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






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






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






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






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






10. Speeding up in a positive direction






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






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






13. 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






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






15. Distance traveled/time






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






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






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






19. 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






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






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






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






23. Energy due to motion






24. Speed and velocity






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






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






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






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






29. Rate of motion of an object






30. Energy due to deformation






31. Linear motion






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






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






34. Rate of motion in a specific direction






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






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






37. 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.






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






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






40. The rate of doing work






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






42. Location in space in relation to a fix point






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






44. The capacity to do work






45. Linear motion






46. 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.






47. Mechanics of objects in accelerated motion.






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






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






50. 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.
