how much does force increase if mass is doubled

F=ma So if m=1 then F=1mIf the mass were to double (m=2) F=2mSo if you are to double the mass, you are essentially doubling the force

First of all, the question is worded somewhat ambiguously because mass does not necessarily imply that there is a force (i.e. an object could be stationary in a system with no gravity and not have a force, or something of the like). Moreover, simply because an object is twice the mass does not mean the force will change. However, we know from Newton's second law that F = ma. Therefore, force will increase or decrease proportionally with mass. This means if an object maintains a contestant acceleration and its mass doubles, the force that it provides will also double.
