“Force and Laws of Motion” is the 9th chapter in the NCERT science textbook of standard IX. An object is recognized to be in motion when its position changes with time. Some effort is required to put a stationary object into motion or to stop a moving object. This effort can be a push or hit or pull. The concept of force is based on this principle. Three fundamental laws that govern the motion of objects were presented by Newton. These three laws are known as Newton’s laws of motion. This resource explains the Second Law of Motion, Third Law of Motion and Law of Conservation of Momentum in detail. The First Law of Motion was explained in detail in part 1 of the series. Let’s read the resource and understand more. Download right away to read it in full.
