Study Guideline

  • Exam 1:
    • Vectors
      • Representation of vectors
        • Graphic representation
          • Graphic definition of operators
        • Linear space and basis:   (3D) a = a1*e1 + a2* e2 + a3*e3
        • Coordination system
          • Polar/spherical coordinates: 2D (r, θ), 3D (r,θ, φ)
          • Cartesian coordinates: (x,y,z)
      • Operators of vectors
        • Unary operator:   +A, -A, etc.
        • Binary operator:  A+B, A-B, αA, A·B, A×B, A∧B, etc.
        • Operators definition using graphic representation and Cartesian system
    • Kinematics
      • Position described as vectors: relative to coordination system
      • Displacement:
      • Velocity:
      • Acceleration:
      • Kinematic models for point
        • constant acceleration motion
        • uniform circular motion
  • Exam 2:
    • Point-Mass Model
      • Newton's three laws of motion
        • Define inertial reference frame which the laws are based upon.
        • Pair-wise only interaction picture

      • Momentum-Impulse Theorem/Newton's Third Law
  • Exam 3:
    • Many Points-Masses Model
      • Descriptions
        • Total mass M=sum(mi)
        • Center of mass   rcm=sum(mi*ri)/M
        • Velocity and acceleration of center of mass: 
        • Center of force  rcfxsum(Fi) = sum(rixFi)
        • Total momentum:  Pnet = sum(mixvi)
        • Total kinetic energy:  Knet=sum(1/2*mi*v2i)
        • Translational kinetic energy:  KT=1/2*M*v2cm
      • Newton's Laws of Motion
        • Second law:     dPnet/dt = Fnet
        • Third law: for an isolated system,    Pnet=const
