1. The problem statement, all variables and given/known data Do rockets have linear or exponential acceleration? 3. The attempt at a solution This is not a homework question I was just wondering if Rockets have linear or exponential acceleration. I was thinking that they have exponential acceleration because of the constant loss of mass due to the exhausted fuel, which in turn makes the rocket lighter and increases its acceleration exponentially. I am not sure if this is correct or not. Please help! EDIT: Say that this is a rocket in deep space where gravity from another body is zero, and the rocket starts from rest.
