What happens to a mass of an object when it moves with the speed of light?
So, does that mean the object will require more energy to move at close to the speed of light?
Yes, that's correct. The closer the object travels to the speed of light, the more energy is required to accelerate it to that speed. This is due to the increase in relativistic mass, which requires more energy to overcome the force of inertia.
