When does kinetic energy equal 0? What is the kinetic energy of a 100 kg cart moving at a speed of 7 m/s? A molecule with mass 5.3E-26 kg has a kinetic energy of 5.8E-21 J. How fast (in m/s) is the molecule moving? A 15 kg mass is traveling at 3 m/s. How...
An object has a mass of 8.99 KG and is moving at 2.55 m/s. How much kinetic energy does it have? A body of mass 2 kg moving with a speed of 10 m per s. Find its momentum. A mass if 10 kg move with a velocity of 4 ms^{-1},Find its kinetic en...
i.e., if we don't understand something we can refer that book for greater detail and depth. I am pretty sure all the books he has mentioned don't use relativistic mass. But he does use it for the reasons mentioned before. PS: I use Quantum Mechanics by Griffiths (hardly ...

It is supposed to bring out the “best” in us; it does no such thing, especially when the competition is for subsistence, or perceived subsistence, it drives us into violence and betrayal. Technology and competition together isolate us from each other, so that next door neighbors no longer...
The mass of a body m does not change when it is in motion and, apart from the factor c, is equal to the energy contained in the body at rest. The mass m does not depend on the reference frame. At the end of the twentieth century one should bid farewell to the concept of mass ...

substantial fraction of the speed of light, special theory of relativity is needed to describe the motion of the particle. This includes the addition of the Lorentz factor. This implies that the momentum of the particle will now be equal to the product of the mass,...
Real matter Ωmatter ~ 0.04 does not exist in the false vacuum. The false vacuum has ω2 > 0 (5.14) The covariant wave propagation operator is Wνν and it depends in its fullness on the choice of connection field that, in turn, depends on which continuous symmetry groups of the ...
Explain Einstein's equation E = mc2 in simple terms. What are the four Maxwell equations? What do they do, and how are they used? What is the dimensional formula of stress? What does Planck's equation mean? What is the best example of differential calculus in...
