That is pretty close to my preferred definition: “force is the rate of transfer of momentum”. Since momentum is a conserved quantity it’s makes sense to speak of transferring it. Both Newton’s 2nd and 3rd laws follow directly from that definition.DrStupid said:The definition of forces says that they are proportioanl (or equal if you use proper units) to change of momentum.
Edit: I see you said as much in a subsequent post!
