Minds on Physics Topics

The Minds On Physics Internet Modules consists of 15 different modules which address the following conceptual ideas. Each module focuses on a topic. That topic is addressed primarily on a conceptual basis. Computational problems are also provided, but typically do not form the central basis of the module. The topics addressed by each module are described below. The objectives are listed elsewhere.

• Kinematic Concepts
  This module has eight sublevels which address such topics as vectors, scalars, distance, displacement, velocity, speed, acceleration, oil drop representations, numerical analysis of data, and average speed and average acceleration calculations.
• Kinematic Graphing
  This module has 11 sublevels which address such topics as the conceptual meaning of slope and area of position-time and velocity-time graphs and the mathematical analysis of such graphs.
• Newton's Laws of Motion
  This module has 12 sublevels which address such topics as mass, inertia, action-reaction forces, equilibrium, balanced vs. unbalanced forces, and the acceleration-net force relationship.
• Vectors and Projectiles
  This module has 10 sublevels which address such topics as vector direction, vector addition, vector resolution, and the horizontal and vertical components of displacement, velocity, acceleration and force for a projectile's motion.
• Forces in 2-Dimensions
  This module has 6 sublevels which address such topics as vector components, equilibrium, the hanging of signs, and inclined planes.
• Momentum and Collisions
  This module has 10 sublevels which address such topics as momentum, impulse, impulse-momentum change theorem, action-reaction forces in a collision, momentum transfer in a collision, and momentum conservation in a collision.
• Work, Energy, and Power
  This module has 10 sublevels which address such topics as work, power, kinetic and potential energy, and the relationship between the mechanical energy of an object and the work done upon or by it.
• Circular and Satellite Motion
  This module has 10 sublevels which address such topics as tangential velocity, centripetal acceleration, centripetal force, inertia, the mathematics of circular motion, satellite motion, universal gravitation, and Kepler's laws of planetary motion.
• Special Relativity
  Not yet available; may be introduced at a future time.
• Electrostatics
  This module has 12 sublevels which address such topics as atomic structure, the nature of charge, insulators, conductors, charging by the methods of friction, induction, and contact, interaction between charged objects, Coulomb's Law, electric fields, and electric field lines.

• Sound and Music
  This module has 11 sublevels which address such topics as the nature of a sound wave, properties of a sound wave, intensity level and the deciBel scale, the Doppler effect, resonance, and standing wave patterns for string instruments and open- and closed-end air columns.
• Light and Color
  This module has 9 sublevels which address such topics as the nature of light waves and the electromagnetic spectrum, the phenomenon of polarization, color addition and subtraction, and the use of color filters.
