Energy and Thermal Physics

Big ideas: More info...

  • The energy of a system can be changed by doing work or heating it.
  • In any event, energy is conserved, but is also dissipated - becoming less easy to put to use.
  • Equilibrium occurs when two or more external influences are in balance (statically or dynamically).

Momentum
Forces and Motion Supporting Physics Teaching

Changing momentum

Things that are already moving require a force acting on them for a certain duration. You can't change the momentum without...
