average vs instantaneous, speed, vectors in kinematics

## Why it matters

The first complete physical theory and the template for all others: kinematics, forces, energy and momentum with Newton's laws.

## Where it is used

Vehicle motion, projectile/ballistics, machine design, sports physics, airbags and safety engineering, robotics.

## How you know you have learned it

Solve ≥10 representative problems with ≥80% adjusted accuracy.
