The 1st law states that 'Things want to keep on doing what they are already doing'.It means that if you kick a ball ,it will keep moving unless it is stopped by some external force. At the same it states that if a thing is in resting position ,it will always be in that position unless some external force is applied on it to make it change its position.This law is also known as the law of inertia. The second law states that' Force is directly proportional to mass and acceleration.This simply implies that harder we kick a ball,farther it will go and vice versa. 3rd law states that there is a action & reaction act in a pair.In simple terms it says that for every reaction ,there is an equal and opposite reaction.
