Energy Forms and Changes

Hooke's Law

Learn about Hooke’s law through this interactive that lets you experiment with force, potential energy, and the physics of springs. Also, connect multiple springs in series and parallel to see additional effects on potential energy stored and Hooke’s law. Html5 required.
Harcourt School

Blackbody Spectrum

This interactive from PhET explores the blackbody spectrum. Learn about thermal radiation as it relates to light intensity by comparing the spectrums of a light bulb, the sun, and oven, and the earth. Then learn how spectral curves and peaks let you tell the energy of a really hot object based on the color it glows. Requires flash.

Temperature: Crash Course Physics

This is a Crash Course video on temperature and the ideal gas law. This video explains the fundamental properties of temperature and heat transfer, touching on a couple of thermodynamic concepts. Requires Html5.

Work, Energy, and Power: Crash Course Physics

This video from Crash Course in collaboration with PBS introduces different forms of work, energy and power. This is a walk through of what these concepts mean from a physics standpoint. Requires html5.

KEY CONCEPTS

Definitions of Energy (PS3.A)

  • Energy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. That there is a single quantity called energy is due to the fact that a system’s total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms. (HS-PS3-1),(HS-PS3-2)
  • At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy. (HS-PS3-2) (HS-PS3-3)
  • These relationships are better understood at the microscopic scale, at which all of the different manifestations of energy can be modeled as a combination of energy associated with the motion of particles and energy associated with the configuration (relative position of the particles). In some cases the relative position energy can be thought of as stored in fields (which mediate interactions between particles). This last concept includes radiation, a phenomenon in which energy stored in fields moves across space. (HS-PS3-2)

Conservation of Energy & Energy Transfer (PS3.B)

  • Conservation of energy means that the total change of energy in any system is always equal to the total energy transferred into or out of the system. (HS-PS3-1)
  • Energy cannot be created or destroyed, but it can be transported from one place to another and transferred between systems. (HS-PS3-1),(HS-PS3-4)
  • Mathematical expressions, which quantify how the stored energy in a system depends on its configuration (e.g. relative positions of charged particles, compression of a spring) and how kinetic energy depends on mass and speed, allow the concept of conservation of energy to be used to predict and describe system behavior. (HS-PS3-1)
  • The availability of energy limits what can occur in any system. (HS-PS3-1)
  • Uncontrolled systems always evolve toward more stable states—that is, toward more uniform energy distribution (e.g., water flows downhill, objects hotter than their surrounding environment cool down). (HS-PS3-4)
