The materials are grouped according to "Unit", roughly covered by each of the
three hour exams in my courses. |
Unit 1
- One-dimensional kinematics. Covers basic algebraic technique
for solving for one unknown in a set of equations involving six variables.
- Vectors. Explains how to resolve two-dimensional vectors into
components in order to calculate the resultant vector.
- Two-dimensional kinematics. Summarizes the type of problems
we will be solving in class and homework.
- Newton's Laws. Explains the concepts of mass, weight, and
mutual interactions of force.
- Dynamics. How to figure out the net force, individual force,
or acceleration in straight-line motion.
|
Unit 2
- Circular motion. Some tricks for relating individual forces
to centripetal force. The role of weight in orbital motion is also covered.
- Work and energy. How to set up the equation of energy conservation
for straight-line motion or free-flight motion.
- Linear momentum and impulse. Explains the concept of momentum
change during collisions. Includes a brief discussion of automotive restraints.

Unit 3
- Rotational kinematics.
- Torque. How to calculate it from the geometry of
a particular case. Includes a discussion of lever arm, and some worked-out
examples.
- Force and torque equilibrium (statics). Explains how to solve
for unknown forces by torque analysis.
- Elasticity, stress and strain.
- Fluid statics. Includes discussion of fluid pressure, buoyancy
and density; with some worked-out example problems. The effects of pressure on the
human body are also discussed.
- Thermal properties of matter. A brief discussion of
pressure, temperature, and root-mean-squared speeds of molecules in an ideal gas.
