... You may (and should) consider forces in the xdirection to be completely separate from forces in the y-direction. The 2nd law states: As long as a force is acting on the object, there must be an acceleration (the equality demands this). This means the velocity must be changing as time changes. Rememb ...

... In equilibrium, all forces cancel out leaving zero net force. Objects that are standing still are in equilibrium because their acceleration is zero. Objects that are moving at constant speed and direction are also in equilibrium. A static problem usually means there is no motion. ...
