[tex]{F}=\frac {{\gamma}^3 {m} {v}^2}{{c}^2} + \gamma {m} {a} [/tex] You all know this equation.Relativistic newton's second law. The problem is as follows: As you know [tex]\gamma[/tex] is dimensionless.So the first term of the right side has dimension of mass.but it should have the dimension of force! what's wrong here? thanks
Hi Shyan. F = dp/dt. However, the equation that you write, I don't know it. See http://en.wikipedia.org/wiki/Special_relativity (scroll down to the section on force). It looks like you forgot a dv/dt term. Harald
