Physics-Classical Mechanics





    Mechanics is a branch of physics that deals with motion and the behavior of bodies under the effect of forces.


    Mechanics Branches
    Figure 1: The branches of Classical Mechanics

    Newton's Law of motion

  1. First Law

    "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force."(Equilibrium/Inertia)

  2. Second Law

    "The force acting on an object is equal to the mass of that object times its acceleration." (Accelerated motion, F = ma)

  3. Third Law

    "For every action, there is an equal and opposite reaction." (Action-reaction)

    Problems

  1. Finding Normal force example 1
  2. A box is sitting on the floor as shown on the figure below, calculate the normal force, N(in kN).
