Questions & Answers

what is nuclear reaction?
Velina Reply
In a chemical reaction, you have atoms being rearranged in different patterns, so you end up with the same atoms but different molecules. In a nuclear reaction, you go one step deeper: you rearrange protons and neutrons, do you end up with different atoms.

So, for example, stars fuse 2 Hydrogen atoms into 1 Helium atom (that's called nuclear fusion). Nuclear reactors break down heavy unstable atoms into smaller ones (that's nuclear fission)

who can explain me about the connecting between energy and work? I don't understand about the equation of the formula
The Reply
Energy can be defined as the ability an object has to do work. so lets say if u want to move something from one place to another you would need energy to do it. a table a certain distance, but if u dont have energy that means you will not be able to move it. Work=Force×distance.
