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
