stationary particle meaning in Hindi

Examples

1. Doesn't this imply that a moving particle has " more gravity " than a stationary particle?
2. A collision between a moving and a stationary particle results in a single moving particle moving in the opposite direction.
3. A vertical displacement causes the two stationary particles to exert a force pushing the particle away from its initial position.
4. The twins paradox arising from Einstein's theory of relativity means that a moving particle will have a slightly different period from a stationary particle.
5. The spherical distribution is unique in that it is essentially the same after a Lorentz transformation, except that a different stationary particle is at the center.
6. In a game of relativistic " billiards ", if a stationary particle is hit by a moving particle in an elastic collision, the paths formed by the two afterwards will form an acute angle.
