1. a object will stay at rest or uniform motion unless acted upon by an external force.
for example, if I were thrown a ball in particular vaccum with no gravity , then the ball would never changes it's velocity..
2.the resulting force of an object will equal the product of mass nd the acc. of an object
F=ma
3.if object a exerts A force on object B object B will exert equal nd opposite force on object A
for example, if I were thrown a ball in particular vaccum with no gravity , then the ball would never changes it's velocity..

1. Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement of inertia, that objects will remain in their state of motion unless a force acts to change the motion.
Ex:-When a basketball player shoots a jump shot, the ball always follows an arcing path. The ball follows this path because its motion obeys Sir Isaac Newton's laws of motion.
2. Newton's second law:- the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. The momentum of a body is equal to the product of its mass and its velocity.
Ex:- If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass. It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one
3. Newton's third law: Every action has equal and opposite reaction
Ex:- Working of rocket
