Relativistic Acceleration
CONSTANT FORCE
The velocity v is derived by knowing the gammafactor γ
and the relativistic momentum p
where the force F, rest mass m and proper acceleration a
are connected with the differential of momentum p over coordinate time t. With that and F=constant we get
Plot with coordinate time t as x-axis (SI-units, momentum and energy as specific quantities per kg rest mass):
Analytical solutions for proper time τ and distance x:

Relativistic Acceleration
CONSTANT COORDINATE ACCELERATION
With α=dv/dt=d²x/dt²=a/γ³=constant the equation for v is simply
With constant coordinate acceleration the speed of light would be reached when

CONSTANT POWER
With constant power L the energy mc²γ inreases linearly with t. The initial energy plus the applied work equals the new energy
where W is the applied work
If we solve for v we get
