Laws of Motion PPT
... 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 object may change – it may eith ...
