Calculating Parallel Circuits (IR1, VR1, IT,) etc...

[BigDanT]

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.
