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






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






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






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






5. The capacity to do work






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






7. Energy due to deformation






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






9. Location in space in relation to a fix point






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






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






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






13. Accelerate our bodies






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






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






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






17. Energy due to motion






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






19. Linear motion






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






21. The muscle elongates is an example of negative work






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 rate of doing work






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






25. Displacement/time






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






27. 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






28. Speeding up in a positive direction






29. 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.






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






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






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






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






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






35. 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.






36. 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.






37. 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






38. Speed and velocity






39. Mechanics of objects in accelerated motion.






40. Rate of motion in a specific direction






41. Distance traveled/time






42. 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






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






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






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






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






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






48. Rectilinear translation and Curvilinear translation






49. Energy due to position






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