Method
Formula, when it applies, and when it does not
Calculate translational kinetic energy and momentum from mass and speed, with its introductory model boundary visible.
KE = ½mv²; p = mv
When
- Translational motion
- Constant mass
- Classical non-relativistic use
Don’t
- This is the classical translational relationship. It excludes rotational energy, deformation, drag, gradients, and relativistic behavior.
