SUMMARY

The discussion centers on Newton's Second Law of Motion, which states that the rate of change of momentum of a body is directly proportional to the net force applied to it. This law clarifies that an object will accelerate when a net force acts upon it, contrasting with Newton's First Law, which asserts that an object in motion will remain in motion unless acted upon by an external force. The conversation highlights the confusion between the two laws, emphasizing the importance of understanding their distinct definitions.

PREREQUISITES

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.
