### 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
• Time-reversal symmetry
• Energy, Work
• Conservative Force/Potential Energy
• Work-Energy Theorem/Newton's Second Law
• Momentum, Impulse
• 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
• Work-Energy Theorem for many points-masses model
• Momentum-Impulse Theorem for many points-masses model
• Special case: rigid body
• Description:
• Kinematic models:
• Constant angular acceleration motion
• Precession (constant magnitude of angular acceleration)
• Special case: elasticity
• Special case: fluid
• Final  Exam (comprehensive):
