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 product of forece multiplied by the time that force acts






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






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






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






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






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






8. 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.






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






10. The capacity to do work






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






12. Energy due to motion






13. 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.






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






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






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






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






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






19. 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.






20. The rate of doing work






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






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






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






24. Mechanics of objects in accelerated motion.






25. Energy due to position






26. 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






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






28. Speeding up in a positive direction






29. Accelerate our bodies






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






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






32. Location in space in relation to a fix point






33. Linear motion






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






35. 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






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






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






38. Displacement/time






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






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






41. 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.






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






43. Distance traveled/time






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






45. The muscle elongates is an example of negative work






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






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






48. Linear motion






49. Rectilinear translation and Curvilinear translation






50. Energy due to deformation
