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. 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.






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






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






4. Speeding up in a positive direction






5. Energy due to deformation






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






7. Rate of motion of an object






8. Energy due to motion






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






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






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






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






13. 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.






14. Rectilinear translation and Curvilinear translation






15. The rate of doing work






16. 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.






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






18. Distance traveled/time






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






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






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






22. Accelerate our bodies






23. Location in space in relation to a fix point






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






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






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






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






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






29. The muscle elongates is an example of negative work






30. 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






31. Speed and velocity






32. Displacement/time






33. 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.






34. 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






35. 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






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






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






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






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






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






41. Linear motion






42. The capacity to do work






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






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






45. Mechanics of objects in accelerated motion.






46. Energy due to position






47. Rate of motion in a specific direction






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






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






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