19. Brief Course Description

Physics is a two semester sequential study of the physical principles that govern the behavior of matter. The course is a math-based physics course. Topics from classical mechanics; such as motion; energy; rotation and gravitation are examined. The course also includes mechanics; electricity; magnetism; electromagnetic radiation; optics; and some kinetic theory. These will be covered at the calculus-based level and the use of calculus in problem-solving and derivations increases as the course progresses. Approximately one week is spent on each chapter.

21. Course Objectives

Motion and Forces

Students know how to solve problems that involve constant speed and average speed.

Students know that when forces are balanced; no acceleration occurs; thus an object continues to move at a constant speed or stays at rest (Newton's first law).

Students know how to apply the law F=ma to solve one-dimensional motion problems that involve constant forces (Newton's second law).

Students know that when one object exerts a force on a second object; the second object always exerts a force of equal magnitude and in the opposite direction (Newton's third law).

Students know the relationship between the universal law of gravitation and the effect of gravity on an object at the surface of Earth.

Students know applying a force to an object perpendicular to the direction of its motion causes the object to change direction but not speed (e.g.; Earth's gravitational force causes a satellite in a circular orbit to change direction but not speed).

Students know circular motion requires the application of a constant force directed toward the center of the circle.

Conservation of Energy and Momentum

Students know how to calculate kinetic energy by using the formula E=(1/2)mv2 .

Students know how to calculate changes in gravitational potential energy near Earth by using the formula (change in potential energy) =mgh (h is the change in the elevation).

Students know how to solve problems involving conservation of energy in simple systems; such as falling objects.

Students know how to calculate momentum as the product mv.

Students know momentum is a separately conserved quantity different from energy.

Students know an unbalanced force on an object produces a change in its momentum.

Students know how to solve problems involving elastic and inelastic collisions in one dimension by using the principles of conservation of momentum and energy.

Heat and Thermodynamics

Students know heat flow and work are two forms of energy transfer between systems.

Students know that the work done by a heat engine that is working in a cycle is the difference between the heat flow into the engine at high temperature and the heat flow out at a lower temperature (first law of thermodynamics) and that this is an example of the law of conservation of energy.

Students know the internal energy of an object includes the energy of random motion of the object's atoms and molecules; often referred to as thermal energy. The greater the temperature of the object; the greater the energy of motion of the atoms and molecules that make up the object.

Students know that most processes tend to decrease the order of a system over time and that energy levels are eventually distributed uniformly.

Students know that entropy is a quantity that measures the order or disorder of a system and that this quantity is larger for a more disordered system.

Waves

Students know waves carry energy from one place to another.

Students know how to identify transverse and longitudinal waves in mechanical media; such as springs and ropes; and on the earth (seismic waves).

Students know how to solve problems involving wavelength; frequency; and wave speed.

Students know sound is a longitudinal wave whose speed depends on the properties of the medium in which it propagates.

Students know radio waves; light; and X-rays are different wavelength bands in the spectrum of electromagnetic waves whose speed in a vacuum is approximately 3◊108 m/s (186;000 miles/second).

Students know how to identify the characteristic properties of waves: interference (beats); diffraction; refraction; Doppler effect; and polarization.

Electric and Magnetic Phenomena

Students know how to predict the voltage or current in simple direct current (DC) electric circuits constructed from batteries; wires; resistors; and capacitors.

Students know how to solve problems involving Ohm's law.

Students know any resistive element in a DC circuit dissipates energy; which heats the resistor. Students can calculate the power (rate of energy dissipation) in any resistive circuit element by using the formula Power = IR (potential difference) ◊ I (current) = I2R.

Students know the properties of transistors and the role of transistors in electric circuits.

Students know charged particles are sources of electric fields and are subject to the forces of the electric fields from other charges.

Students know magnetic materials and electric currents (moving electric charges) are sources of magnetic fields and are subject to forces arising from the magnetic fields of other sources.

Students know how to determine the direction of a magnetic field produced by a current flowing in a straight wire or in a coil.

Students know changing magnetic fields produce electric fields; thereby inducing currents in nearby conductors.

Students know plasmas; the fourth state of matter; contain ions or free electrons or both and conduct electricity.

C. COURSES ONLY

27. Indicate how this course is different from the standard course.

Physics is designed to give students experience with Physics concepts and applications comparable to that in a first year college Physics class. Students in Physics engage in an in-depth study of advanced mathematics-based Physics connecting the study of key formulae with the physical phenomena they observe on a day-to-day basis. Physics requires that students broaden the scope of their scientific study while developing the skills necessary for authentic scientific investigation.
