Practice Model of Water - 3.2.1 Internal Energy (GCSE Physics AQA)

Internal Energy

Energy of Particles

  • Particles have kinetic (KE) and potential (PE) energy. In a system, particles mainly have 2 different types of energy. Kinetic energy allows the particles to move. Potential energy is the energy that keeps the particles in their positions.
  • Internal energy is the total KE and PE. In the system, if you combine all the kinetic energy and potential energy, and this will give you a value for the internal energy.

Internal energy is the total kinetic energy and potential energy of all the particles (atoms and molecules) that make up a system.

Where:

  • internal Energy (U) = Joules, J
  • kinetic Energy (Ek) = Joules, J
  • potential Energy (Ep) = Joules, J
