force dose not equal mass.


 * $$m= \frac{f}{a}= \frac{w}{g} $$

mass in special relativity
 * $$m = \frac{\sqrt{E^2 - \left(p c\right)^2}}{c^2} $$

The relativistic mass equation is the formula for E divided by c2

m_{\mathrm{rel}} = { m \over \sqrt{1-{v^2\over c^2}}} $$
 * $$f_x = m \gamma^3 a_x =  m_L a_x, \,$$
 * $$f_y = m \gamma a_y  = m_T a_y, \,$$
 * $$f_z = m \gamma a_z  = m_T a_z. \,$$
