Engineers use mathematics and physics to build simplified models of the real world. These models let us:
Math is the language of patterns, and physics describes how the universe behaves. Together they give engineers a foundation for building models that are simple but useful.
This is a way to check whether equations make sense — by comparing units. For example, if you calculate a force using speed and distance, something’s probably wrong!
These diagrams show all the forces acting on an object. They help engineers visualize interactions before writing equations or building prototypes.
If you push a cart with twice the force, it accelerates twice as much (in ideal conditions). This is a model based on Newton’s Second Law: Force = Mass × Acceleration.
Imagine you’re choosing between two wheels for a design: one heavy and one light. Which would you pick for speed? For strength? What tradeoffs are you considering?
