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.
an object is accelerating at 2 ft/s^2. if the net fore is tripled and the mass is doubled, then what is the new acceleration
