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 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






2. 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.






3. Speed and velocity






4. The rate of doing work






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






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






7. Rectilinear translation and Curvilinear translation






8. 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.






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






10. 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






11. Mechanics of objects in accelerated motion.






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






13. The capacity to do work






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






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






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






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






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






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






20. Linear motion






21. 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.






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






23. Rate of motion in a specific direction






24. Energy due to deformation






25. 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.






26. Location in space in relation to a fix point






27. Energy due to motion






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






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






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






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






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






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






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






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






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






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






38. Linear motion






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






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






41. Accelerate our bodies






42. Energy due to position






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






44. Rate of motion of an object






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






46. Speeding up in a positive direction






47. The muscle elongates is an example of negative work






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






49. 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






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