... • Friction is the "evil monster" of all motion. Regardless of which direction something moves in, friction pulls it the other way. – Move something left, friction pulls right. Move something up, friction pulls down. • It appears as if nature has given us friction to stop us from moving anything. ...

... A. Newton’s First Law of Motion – An object at rest remains at rest and an object in motion remains in motion at constant speed and in a straight line unless acted upon by an unbalanced force. 1. In other words, if you don’t have a force, or net force is zero, you can’t have acceleration. 2. If you’ ...
