Work increases or decreases over displacement.- Kinetic Energy equals one half mass times velocity squared
- Work equals change in Kinetic Energy, which is equivalent to final kinetic energy minus initial kinetic energy.
- Work equals force over displacement (If the force and displacement are parallel).
- Work equals Force over displacement times cos theta (If the force and displacement are at an angle to each other. Theta is the angle formed from Force and displacement).

- Vector A dot product Vector B is equal to the scalar value of magnitude A times magnitude B times cos theta.
- Work (scalar value) equals the dot product of Force times displacement, which is equal to magnitude of Force times magnitude of displacement times cos Theta.
- Dot Products distribute.
