What is adding forces in a straight line?Show answer
When forces act along the same line, you combine them into a single resultant force:
What is equilibrium?Show answer
An object is in equilibrium when the resultant force on it is zero. In equilibrium an object is either at rest, or moving at a constant velocity in a straight line (this is just Newton's first law again).
