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, AB, 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:
 PointMass Model
 Newton's three laws of motion
 Define inertial
reference frame which the
laws are based upon.
 Pairwise only
interaction picture
 Timereversal symmetry
 Energy, Work
 Conservative Force/Potential Energy
 WorkEnergy Theorem/Newton's Second Law
 Momentum, Impulse
 MomentumImpulse Theorem/Newton's Third
Law
 Exam 3:
 Many PointsMasses Model
 Descriptions
 Total mass M=sum(m_{i})
 Center of mass
r_{cm}=sum(m_{i}*r_{i})/M
 Velocity and
acceleration of center of
mass:
 Center of force r_{cf}xsum(F_{i})
= sum(r_{i}xF_{i})
 Total momentum: P_{net}
= sum(m_{i}xv_{i})
 Total kinetic energy:
K_{net}=sum(1/2*m_{i}*v^{2}_{i})
 Translational kinetic
energy: K_{T}=1/2*M*v^{2}_{cm}
 Newton's Laws of Motion
 Second law:
dP_{net}/dt = F_{net}
 Third law: for an
isolated system,
P_{net}=const
 WorkEnergy Theorem for many
pointsmasses model
 MomentumImpulse Theorem for many
pointsmasses model
 Special case: rigid body
 Description:
 Kinematic models:
 Constant angular
acceleration motion
 Precession (constant
magnitude of angular
acceleration)
 Special case: elasticity
 Special case: fluid
