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






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






3. Distance traveled/time






4. Rate of motion of an object






5. Speeding up in a positive direction






6. Mechanics of objects in accelerated motion.






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






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






9. Speed and velocity






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






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






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






13. 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






14. Accelerate our bodies






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






16. Energy due to motion






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






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






19. Linear motion






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






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






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






23. Rectilinear translation and Curvilinear translation






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






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






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






27. 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.






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






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






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






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






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






33. The muscle elongates is an example of negative work






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






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






36. Displacement/time






37. The rate of doing work






38. Linear motion






39. 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






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






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






42. Energy due to position






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






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






45. 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.






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






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






48. 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






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






50. Location in space in relation to a fix point
