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