    Hard Stuff

    Can anyone explain to me what Newtons 2nd law means?

    ?? Neither "hard stuff" nor "Calculating parallel circuits"!!

    Newton's second law means exactly what it says: If a moving object has absolutely no forces acting on it then it will continue to move in a straight line at constant velocity".

    You could say that "means" that only a force will change the speed or direction of motion of a body.

    ...er .....Isn't that Newton's First Law?

    The Second law states that the rate of change of momentum of a body is directly proportional to the net force applied to it. Or in simple terms, if there is a net force acting, a body will accelerate.
