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.
