Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motionstays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.



Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.



Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.



Conservation of momentum is a fundamental law of physics which states that the momentum of a system is constant if there are no external forces acting on the system. It is embodied in Newton's first law (the law of inertia).


I hope it helps to you ☺☺

Explanation:

 \mathbb{YOUR \: ANSWER \: IS}

Newton's first law of motion :-

An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force.

Newton's second law of motion:-

The second law of motion states that the rate of change of momentum of an object is directly proportional to the applied unbalanced force in the direction of force.

Newton's third law of motion :-

The third law of motion states that when one object exerts a force on another object , the second object instantaneously exerts a force back on the first.

Law of conservation of momentum:-

sum of momenta (plural form of momentum)of the two objects before collision is equal to the sum of momenta after the collision provided there is no external unbalanced force acting on them.
