When nucleons i.e. protons n neutrons come close to each other to form nucleus, some mass is lost as mass defect i.e. the mass of resultant nucleus is lesser than that of total mass of its constituents. This mass is actually not lost but is converted into energy which helps the nucleons to stay together. This energy is known as nuclear binding energy.

What is Top Ten Hardest Physics Topics 09ShamsulBahriel Physics is number one my best things to learn. But, there's something that you may fed up when you learn them. The Top Ten 1 Electromagnetism It took time and patience to learn this properly, and even then, I'm confused when to use the Left-Hand Rule, and when to use the Right-Hand Rule. But it's more interesting than any other topic, definitely. c M+1 EM is the basis of almost everything, yet there are not too many good professors who can teach it in an intuitive manner. So definitely the hardest topic, hands down! c M It is about six years ago since I studied physics and I can still remember very well how tough electromagnetism was c M First test that I failed in engineering, congrats electromagnetism. c Mnew V 2 Comments Vote E 2 Quantum Mechanics Well, Niels Bohr said that anyone who is not shocked by quantum theory has not understood it. Quantum Mechanics are fascinating, but I know that even the greatest of minds see it as hard. I love Quantum Mechanics from Heisenberg to Schroedinger. c M+8 Dear quantum mechanics I don't love you but why You love me :( c M+2 It is very fun, but that doesn't make it less difficult. c M+1 Quantum, quantum, quantum, when will you ever be nice to me?!?!?! c Mnew V 1 Comment Vote E 3 Projectile Motion Projectile motion, while being one of the first things students learn in physics, is actually one of the most difficult to grasp and enigmatic entities in the entirety of physics. Richard Feynman once said, "Projectile motion. A topic of immense importance and of utter confusion. If you throw a ball with a known initial velocity, and you know something about the medium it travels through as well as gravity, you can know exactly where it will land. How in the world does this work? It is enigmatic". The true mysteries of projectile motion are still yet to be discovered and can only be postulated as of today's research. c M You guys must be kidding, any regular physics student can eat this, by looking at the other topics I can say that the one who made this list is a kid c M+5 I struggled so much with projectile motion. I think it must be one of the hardest things besides Newton's First Law. Maxwell's Equations were wicked easy though, I don't understand why we don't start with those. c M+1 Projectile motion is not hard, its fairly easy. I would say quantum mechanics is the hardest c Mnew V 5 Comments Vote E 4 Relative Velocity This topic has always made me suffer in physics. Rest of all the topis mentioned are quite easy. This is not a topic in modern physics. Slope problems are damn easy c M+3 Vote E 5 Electronics Vote E 6 Radiation It's actually not difficult, if you love the amazing world of physics.. then it's certainly not ( trust me it's great ) - Ananya c M Vote E 7 Force Vote E 8 Motions Vote E 9 String Theory One of the most specialist areas in all of Physics. Most of Physics, nailed it and love it, but String Theory just drives me this way and that! But it's still awesome, despite the fact that it's entirely mathematical and isn't tested yet. c M+4 Vote E 10 Other Creatures Show the all others c M+5 Vote E The Contenders 11 Pressure Hardest ever c M Vote E 12 Electricity Electrons have dual nature same as light c M+1 Actually this is vast yet very easy if you use the Laws in a practical manner like Maxwells laws,Flemings law,Ohms law etc.First understand the concept android try it practically it will sink in your brain. c M V 1 Comment Vote E 13 General Relativity It is a very interesting topic to learn, but also very confusing at times, the hardest of any other theory of relativity. I don't think you can learn it just by reading, you need to see what happens with animations just to get a glimpse of what's happening, unlike many different topics in physics. c M+2 V 1 Comment Vote E 14 Astronomy Easy - TheRemixr c M Vote E 15 Thermodynamics Man this is the best yet one of the most difficult in physics c M+3 Best and interdisting c M This sucks c M Vote E 16 Black Holes What a fantastic topic but need patience to understand c M Just think about it... c M Vote E 17 Rocket Science V 1 Comment Vote E 18 Simple Harmonic Motion The worst and most difficult topic ever! tons of formulas, no matter how hard I try, I just can't understand it. :( c M Vote E 19 Dark Energy's
