2. Laws of Motion
... What is Newton’s second law? If the resultant force acting on an object is not zero, all the forces are said to be unbalanced. This forms the basis of Newton’s second law of motion, which states: If the forces on an object are unbalanced, two things about the object can change: the speed of the o ...

... --If you can, use the resulting expression to solve for the unknown you are seeking. If not, and you find more unknowns in the relationship than you have equations, either repeat the process along the other coordinate axis or, if that doesn't help, pick another body in the system and start the whole ...
