Why the mass increase at close to light speed?
Why does mass increase with velocity as an object approaches the speed of light?
Can the speed of light be increased? What happens to an object if it reaches the speed of light? How does the mass of an object affect kinetic and potential energy? Given that photons have no mass and the speed of light cannot be exceeded, could there be a negative mass that exceeds the speed of light? Why does an object with a large mass have more potential energy than a smaller mass object? If an object increases in velocity due to an acceleration, and the acceleration itself decreases, then what effect does that give to the object? Does an object having greater mass have greater weight and greater density? Why is the speed of light the limit for how fast a physical object can move? Does a moving photon have mass? F=mass×acceleration then why don't more massive objects accelerate faster towards Earth? Does gravity affect the speed of light? Does gravity affect the speed of light? What would happen if an object would reach the speed of light? What would happen to object if it moves faster than speed of light? If light does not have mass, then how does it have momentum? Does energy have mass or light (as in light beam) have mass? Why we cannot make a vehicle which can move at a speed greater than the speed of light? If an object could travel at the speed of light, what would happen to it? If in theory an object reached the speed of light what would happen to it? Why do mass and energy affect space-time? Do massless particles have to travel at the speed of light? The force of gravity is greater for more massive objects. Why don't more massive objects accelerate faster towards Earth? Since the speed the universe is expanding is increasing what will happen when we reach the speed of light? If a moving particle had infinite mass at rest wouldn't that mean that whatever speed it has it would have infinite mass/energy? Does light have mass? Less Volume individual Mass creates more actual life than invidual larger mass? Does mass have an affect on gravity? What happen if we moving with the speed of light? In what way mass affects gravity? Do photons, the particles of light, have mass?
