What does static equallibrium mean in mechanics for an object which can move in a two dimensional space? Select all that apply. 1. The object is moving. 2. The object is not moving. 3. Assume that x and y directions are perpendicular to each other. The sum of all the forces on the object is zero in the x direction, but not in the y direction. 4. The sum of all the forces on the object is zero in the y direction, but not in the x direction. 5. The sum of all the forces on the object is zero in both the x and y directions, but not necessarily in all other directions.
