Homework Help: Physics

Posted by Mary on Tuesday, April 3, 2007 at 1:34am.

Newton's second law states that if an object has zero acceleration, the net force acting on it is zero.

My question is if you have an object at constant acceleration moving downward is there a net force being applied to it?


Does constant acceleration= zero net force?

Yes, for course. Remember that acceleration is a vector, so net force= mass *acceleration. If acceleration is not zero, force is not zero.
