Concepts of energy such as: o The relationship between heat and temperature for example:  Heat energy consists of the random motion and vibrations of atoms, molecules and ions  The higher the temperature, the greater the atomic or molecular motion o The First and Second Laws of Thermodynamics – the conservation of energy and concept of entropy o The distinction between kinetic and potential energy o How energy can be transferred from one form to another o The basic principles of optics o The basic principles of electricity and magnetism o Series and parallel circuits

•

Concepts and principles that explain motion such as: o Newton’s law as a classical description of motion for example:  A force is required to alter an object’s motion  The absence or balance of force no change in motion is observed  How forces are additive and the motion of an object is determined by the cumulative effect o The characteristic properties of sound and electromagnetic waves that have energy, transfer energy when the interact with matter, and have properties that include:  Wavelength, frequency, amplitude, speed, absorption, reflection and refraction o The range of the electromagnetic spectrum (e.g., radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, xrays, and gamma rays) o The electromagnetic waves result when a charged object is accelerated and that the energy of electromagnetic waves is carried in wave packets whose energy is inversely proportional to the wavelength Concepts of force such as: o The general concept of gravitational force o How materials that contain equal amounts of positive and negative charges are electrically neutral, but that a very small excess or deficit of negative charges in material produces noticeable electrical forces o The relationship between magnetic and electric fields can be thought of as different aspects of a single electromagnetic field Concepts of modern physics such as: o Special relativity for example:  In contrast to moving objects, the speed of light is the same for all observers, no matter how they or the light source happen to be moving  That nothing can travel faster than the speed of light o How constituent particles make up atoms and how a general understanding of physical locations of each
