Please explain nuclear fusion!!Watch
If two light nuclei join together to form a “heavier” nucleus, then how is the mass of the nucleus less. I know the mass is less because of some of it being converted to energy but wouldn’t that mean it becomes “lighter” instead? Because weight is influenced by mass. What does it mean by the nucleus becoming “heavier”?? I sound kinda dumb asking this.
Simplified example and probably not the right numbers, but essentially nuclei of masses 2 and 3 fuse to make one of mass 1 and one of mass 3.99. The 0.01 left over is cinverted to energy.
