7 equations every engineer should understand, not just know:
1. F = ma (Newton's Second Law)
Force = mass × acceleration.
Everything that moves or is prevented from moving obeys this. Every structural load, every vehicle dynamics problem, every rocket trajectory.
2. σ = F/A

Kinetic energy being equal to half mass times velocity squared (the general case of the relativity equation) is an insanely big deal in everyday life.
That and the surface to volume ratio explain so much about our reality!
