Force

  • a force is described as an exchange of bosons between the objects affected, such as a photon for the electromagnetic force and a gluon for the strong interaction. These particles are called force carrier particles

Force - Measurement

Newton (𝑁) is the International System of Units (SI)derived unit of force

  • 𝑁 = 𝑘𝑔·𝑚/𝑠2

Electroweak Interaction Theory

  • the Standard Model has united electromagnetic interactions and weak interactions into one unified interaction called electroweak
