When designing particle accelerator experiments, relativistic effects must be taken into account.

The particles' behavior must be analyzed relativistically when their speeds approach that of light.

As a committed relativist, she argued that moral judgments depend on cultural context.

Many relativists argue that moral standards vary with cultural context.

The relativistic masses of particles increase with velocity, complicating calculations at speeds close to the speed of light.

The professor explained how non-relativistic quantum mechanics differs from relativistic theories during the lecture.

As the spacecraft approached light speed, the physicist explained that its relativistic mass would increase significantly from the viewpoint of an outside observer.

In modern physics courses, relativistic mechanics explains why time dilation and length contraction occur at speeds close to the speed of light.
