Explain why the fission of heavy nuclei releases energy. Similarly, why is it that energy input is required to fission light nuclei

electrical to thermal

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
