Question

From where the contact forces of mechanics are fundamentally derived?

Answer 1

Contact forces:

1. The forces that are generated due to the physical contact between two bodies are known as contact forces.
2. Contact forces of mechanics fundamentally arise from electromagnetic forces.
3. There are many types of contact forces. These are surface tension air resistance, friction, upthrust, applied force, normal force, and muscular force.
4. The macroscopic object interaction can be signified as resulting from electromagnetic interactions.
5. Mainly interactions are between protons and electrons of the atomic constituents of these objects.
6. All bodies are made of charged constituents at the microscopic level.
7. The various contact forces arising due to the elasticity of bodies, molecular collisions, etc. can ultimately be traced to the electrical forces between the charged constituents of different bodies.

Hence, the contact forces of mechanics are fundamentally derived from electromagnetic forces.
