Precedent (design) - an earlier example or guide to be considered in subsequent similar circumstances. 

Symmetry - in everyday life refers to a sense of harmonious and beautiful proportion and balance. In geometry, identically mirrored across an axis. 

Aerodynamic - having a shape which reduces the drag or friction from air particles moving past.

Hatch (design) - an artistic technique used to create tonal or shading effects by drawing closely spaced parallel lines

Acceleration - The rate at which an object changes velocity. Often measured in the units of (m/s²)

Inertia - the tendency of objects in motion to stay in motion, and objects at rest to stay at rest, unless a force causes its speed or direction to change.

Grit (sand paper) - a rating of the size of the abrasive particles embedded in the sandpaper. The lower the grit the faster the sanding

Critique (design) - analyzing a design, and giving feedback with the goal of improvement.

Thrust - When a vehicle expels mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that vehicle 

Newton (unit of force) - force that would give a mass of one kilogram an acceleration of one meter per second per second

Primer (painting) - a preparatory first coating before painting. Priming ensures better adhesion of paint  and provides additional protection for the material being painted.

Coats (painting) - when painting, multiple layers are often applied once the first layers are dried to achieve a more complete covering of paint

Drag Coefficient - quantifies the resistance of an object relative to its frontal area as it moves through a fluid.

Exponential - exponential increase is a process that increases quantity over time at an ever-increasing rate.
