Notes - Net Forces and Applications of Newton`s Laws
... Advanced Look at Weight It is easy to see that the force of gravity acts on an object when it is falling. When an object is at rest on a surface, the gravitational force still continues to act. According to the second law, only a net force would cause the motion of the object to change. Since the ob ...

... If we do work against gravity, by raising an object a height h, we can get that work back when the object is lowered. This is a consequence of being a conservative force. One way to think of this is that when we do work against gravity, this work is stored in some way for retrieval later. This idea ...

... c) As calculated in part (b) the max value of the static friction force is 8N. So we will need a force just a bit larger than 8N to make it move. d) If the box is to keep moving at constant speed we have to apply a force to balance the force of kinetic friction. Ff = mk FN = 0.1 x 40N = 4N is the fo ...
