1. The problem statement, all variables and given/known data Impulse is defined as: force x time a) Find its unit expressed in term of the base units. b) What quantity has the same unit? What could it mean? (Impulse = change in momentum) 2. Relevant equations I = F x T P = mv 3. The attempt at a solution a) First, we convert the force into its base unit, and then we solve. I = F x T = ML/T^2 x T = ML/T b) L/T is v so [F x T] = [mv] [Impulse] = [Momentum] Therefore, momentum has the same unit as impulse. My problem is with the second part of question b. I know without the hint given in parenthesis that impulse and momentum are related, but what is it that they want me to explain? I found the question "What could it mean?" very vague, and I don't really know how I am supposed to answer it.
