Force and Motion
... Force is something that can change the motion (velocity) of an object. It is due to the interaction between objects. Therefore, it exists in pairs. Force is a vector quantity. It has both magnitude and direction. Its SI unit is newton (N) Force can be measured by a spring balance. Forces can be clas ...
