    (1) newtons law of motion (1) newtons law of motion Presentation Transcript

    • Newton’s Law of Motion
    • Newton’s First Law of Motion
      • Every body continuous in its state of rest, or uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.
      • Inertia
      • The tendency of an object to resist any attempt to change its velocity
      • Mass
      • A measure of the inertia in the body.
      • Mass is a scalar quantity and obeys the rules of ordinary arithmetic
    • Newton’s Second Law of Motion
      • The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
    • Weight distinguished from mass
      • Weight
          • The weight of the body is that force exerted on the body by the pull of gravity.
          • The basic relationship of FORCE and MASS is the 2 nd Law of Motion:
          • In gravitational case:
    • Newton’s Third Law of Motion In every action there is always opposed an equal reaction.
    • Important Terms:
      • Tension
          • Forces which tend to PULL matter apart along some axis
      • Compression
          • Forces which tend to PUSH matter apart along some axis
      • Friction
          • Force that acts to oppose the start or continuance of sliding motion between surfaces
    • Free-Body Diagram, FBD
      • Free-body diagram is a pictorial representation often used by engineers to analyze the FORCES acting on the body. And the body is isolated from any effects of the surroundings.
    • Sample Problem 1:
      • Draw the free-body diagram of the following:
    • Sample Problem 2:
      • Draw the free-body diagram of the figure shown
    • Seatwork: Draw the free body diagram of the following:
    • Assignment:
      • Draw the free body diagram of the following:
    • For next meeting:
      • Define the following:
      • Line of action
      • Equilibrium
      • Conditions of equilibrium
      • Static equilibrium
      • Dynamic equilibrium
      • Questions:
