force = mass * acceleration
ma=F(mass)(acceleration)=Force
Isaac Newton, in his third law, stated that "The acceleration produced by a net force on an object is directly proportional to the magnitude of the net force, is in the same direction as the net...
(Force on an object) = (the object's mass) times (its acceleration)
These three variables are related by Newton's Second law: Force = mass x acceleration.
Both mass and acceleration will remain constant but speed will increase. Its explained in Newtons second law, in short: F=m*a
