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, $F = \dot p$.
Mass: Mass is a measurement of the amount of matter in a sample; fundamentally, it is a. measurement of how much influence gravity has on the sample. In the metric system, mass is. measured in grams (g). Mass is determined in the lab by using an electronic scale; the scales that we. will use are accurate to 0.001 g.
