Key Stage 5
Meaning
The law of conservation of mass-energy is the observation that the total mass-energy in a closed isolated system remains the same before and after all fundamental interactions between particles.
About Conservation of Mass-Energy
- Mass-Energy Equivalence means that energy and mass are interchangeable under certain conditions.
- In a fundamental interaction between subatomic particles mass-energy is conserved. This is used to create new particles by causing particles to collide with extremely large kinetic energies allowing this kinetic energy to be converted to mass.
