I have noticed just in the past couple of years that I get a red splotchy rash on my neck when I drink beer. I thought it might be an allergic reaction, but it doesn't happen all of the time when I drink beer. I have tried switching to a different kind of beer, but I still have random outbreaks of this rash. Answer.
So, if two objects have the same energy $E_k$, they only have the same momentum if they also have the same mass. Since the bull has a much larger mass than the bullet, it must therefore have a much larger momentum than the bullet to arrive at the same kinetic energy. Force is change of momentum with time, $F = \dot p$.
Both Mass Number and Atomic Mass are very closely related to each other and indicates the weight of elements. They differ in the way they are defined. The main difference between mass number and atomic mass is that mass number deals with individual atoms taken into consideration separately whereas atomic mass deals with the weighted average of the element including its isotopes. What is Mass Number. As mentioned above, the mass number is associated with the weight of a single atom under consideration.
