Calculate force from mass and acceleration using Newton’s second law.
Newton’s second law relates net force to the acceleration it produces. Multiplying force by the time it acts gives impulse, which equals the change in momentum. It is the net force that matters: a heavy object moving at constant speed needs zero net force however much thrust is applied against friction.

F = m a Newton’s second law relates net force to the acceleration it produces. Multiplying force by the time it acts gives impulse, which equals the change in momentum.
