Term1/14
What is nuclear energy
Definition1/14

Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe. Energy is what holds the nucleus together. There is a huge amount of power in an atom's dense nucleus. Nuclear energy is seen when nuclear fusions or fissions happen.

How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent
Definition1/14

If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.

Term1/14
Does speed affect gravitational potential energy of an object
Definition1/14

Does speed 'effect' the gravitational potential energy of an object? No, but gravitational potential energy can be converted into kinetic energy - so the gravitational potential energy can effect the speed.

Ep = mgh

Energy Potential = mass * 9.81 (gravity) * height

Speed / Velocity is absent from that equation.
