Question

1):-Newton First law of motion.
3):-Newton Second law of motion.
3):-Newton Third law of motion.​

Answer 1

Answer:

First Law of Motion

A body continues to be in the state of rest or uniform motion in a straight line unless acted upon by an external unbalanced force. The First Law is also called the Law of Inertia.

Second Law of Motion

Momentum

Impacts produced by objects depend on their mass and velocity. The momentum of an object is defined as the product of its mass and velocity. p = mv. Vector quantity, has direction and magnitude.

Third Law of Motion

Newton’s 3rd law states that every action has an equal and opposite reaction. Action and reaction forces are equal, opposite and acting on different bodies.

Answer 2

Answer:

1. Newton's First Law of Motion : Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.
2. Newton Second Law of Motion : Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
3. Newton Third Law of Motion : Newton third law states that if an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
