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 muscle elongates is an example of negative work






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






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






4. The capacity to do work






5. Rectilinear translation and Curvilinear translation






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






7. Rate of motion of an object






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






9. The rate of doing work






10. 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.






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






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






13. Energy due to position






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






15. Mechanics of objects in accelerated motion.






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






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






18. Energy due to motion






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






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






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






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






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






24. Distance traveled/time






25. 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.






26. 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.






27. Location in space in relation to a fix point






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






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






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






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






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






33. Linear motion






34. Accelerate our bodies






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






37. Speed and velocity






38. 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






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






40. Speeding up in a positive direction






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






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






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






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






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






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






48. Energy due to deformation






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






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