Regents Physics Course Outline

Regents Physics Topics of Study
  1. Mechanics
    1. Linear motion
      1. Vectors vs scalars
      2. Constant velocity vs accelerated motion
      3. Friction cause falling objects to deviate from theoretical path
    2. 2D motion
      1. Vector addition and resolution
      2. Vertical and horizontal independence
      3. A projectile's time of flight is dependent upon the vertical component of its motion
      4. Range is dependent on horizontal velocity and time of flight
    3. Newton's Laws
      1. No net force results in no acceleration
      2. An unbalanced force causes acceleration
      3. Weight is the gravitational force of attraction
      4. Kinetic friction opposes motion
      5. Forces occur in action / reaction pairs
    4. Circles, planets, and springs
      1. Centripetal force produces centripetal acceleration and is directed perpendicular to the tangential velocity
      2. Hooke's law and energy in a spring
      3. Universal gravitation and the inverse square law
    5. Momentum and impulse
      1. Momentum is conserved in a closed system
      2. Impulse is a change in momentum
  2. Energy and Power
    1. Types of energy
      1. Height increases potential energy
      2. Speed increases kinetic energy
      3. Friction increases internal energy
    2. Work-energy theorem
      1. Work done changes total energy of the system
      2. All energy transfers are governed by the law of conservation of energy
      3. Power is the rate at which work is done
      4. Ideal vs non-ideal systems
      5. In an ideal mechanical system the sum of kinetic and potential energy is constant
      6. In a non-ideal system, as mechanical energy decreases there is a corresponding increase in other energies such as internal energy.
  3. Electrostatics and Circuits
    1. Electric forces and fields
      1. Electric and magnetic forces may be attractive of repulsive
      2. Electric fields and forces are governed by the inverse square law
    2. Current and electric circuits
      1. The factors effecting resistance in a conductor are length, cross-sectional area, temperature, and resistivity.
      2. Common metallic conductors follow Ohm's law at constant temperatures.
      3. Electric power and energy can be determined for electric circuits.
      4. Diagrams and analysis of simple parallel and series circuits.
    3. Magnetism
      1. Moving electric charges create magnetic fields
      2. Energy can be stored in electric of magnetic fields.
      3. Compass behavior and magnetic force of attraction.
  4. Waves and the Electromagnetic Spectrum
    1. Physical waves
      1. Oscillations produce waves
      2. Waves carry information and not mass
      3. Waves are categorized as transverse or longitudinal
      4. Mechanical waves require a medium to travel through
      5. The model of a wave includes characteristics of amplitude, wavelength, frequency, period, speed, and phase.
    2. The electromagnetic spectrum
      1. Electromagnetic radiation can travel in a vacuum.
      2. When a wave strikes a boundary reflection, transmission, and absorption occur. Often refraction occurs as well.
      3. Refraction of a light wave depends on the indices of refraction of the two interacting mediums.
      4. Speed of a light wave in inversely proportional to the index of refraction.
    3. Wave phenomena
      1. Superposition of waves
      2. Resonance causes sympathetic vibrations
      3. Diffractions is dependent on wavelength and the size of the opening
      4. The Doppler effect is due to the relative motion between the source and observer. This causes red and blue shift.
  5. Modern Physics
    1. Models of the atom
      1. Energy and matter exhibit characteristics of both waves and particles at the sub-atomic level
      2. Rutherford's model, Thompson's model, Bohr's model
    2. Energy of the atom and photons
      1. Mass and energy of atoms are always conserved
      2. Energy of matter is restricted to discrete values
      3. The energy of a photon is proportional to its frequency
    3. The Standard Model of Particle Physics
      1. Charge is quantized at the atomic and the sub-atomic level
      2. The nucleus is a conglomeration of quarks which manifest themselves at protons and neutrons.
      3. Each elementary particle has a corresponding antiparticle.
