Antiparticles and rest energy

Antiparticles and rest energy

Antiparticles are partners of ordinary particles. They have the same mass and the same rest energy as the corresponding particle, but opposite charge, so an electron has charge −1.60×10−19 C-1.60 \times 10^{-19} \, \text{C}−1.60×10−19C and a positron has +1.60×10−19 C+1.60 \times 10^{-19} \, \text{C}+1.60×10−19C.

Step-by-step lessons on AQA A Level Physics Particles, antiparticles and photons. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
