    mass times acceleration, but I believe there is probably more to your question than you asked. Can you expand on what you need?

    f=ma; as above force in Newtons mass in grams and acccelleration in \[m^{-2}\] (meters per second per second)

    force is defined by newtons 2nd law of motion F = ma if m = mass in kilograms and a = acceleration is in meters per sec per sec then the force is in Newtons.

    A Newton is the force which gives a mass of 1 kilogram an acceleration of 1 m/s/s

    what newton said was that force equals to the rate of change of momentum.F=ma only if the mass is invariable... lets see why: f=rate of change of momentum f=dp/dt f=d(mv)/dt f=m*dv/dt+v*dm/dt if dm/dt(varying mass)=0 then only f=ma. but thats not the case everywhere,for example, in rocket propulsion where the mass and velocity both are changing. so rate of change in momentum is the newton theory,or the theory which we should use to keep our concepts clear!!!!
