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. Rectilinear translation and Curvilinear translation






2. 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.






3. Distance traveled/time






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






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






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






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






8. Accelerate our bodies






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






10. 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






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






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






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






14. Energy due to deformation






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






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






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






18. Displacement/time






19. The muscle elongates is an example of negative work






20. The capacity to do work






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






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






23. 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






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






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






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






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






29. Location in space in relation to a fix point






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






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






32. 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






33. Rate of motion of an object






34. 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.






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






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






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






38. Mechanics of objects in accelerated motion.






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






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






41. Linear motion






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






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






44. The rate of doing work






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






46. Rate of motion in a specific direction






47. 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.






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






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






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