|
Every body maintains its initial state rest or motion unless no external force is applied
|
|
|
The rate of change in momentum of a body is directly proportional to the applied force on the body and takes place in the direction of force
|
|
|
To every action there is equal and opposite reaction
|
|
|
None of above

Detailed explanation-1: -Newton’s first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.
Detailed explanation-2: -Newton’s First Law of Motion states that a body at rest will remain at rest unless an outside force acts on it, and a body in motion at a constant velocity will remain in motion in a straight line unless acted upon by an outside force.
Detailed explanation-3: -The first law of motion is stated as: 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. In other words, all objects resist a change in their state of motion.
Detailed explanation-4: -We call Newton’s first law is known the law of inertia because it states that every material body has a property that allows it to resist changes in its state of rest or motion.
Detailed explanation-5: -In the first law, we understand that an object will not change its motion unless a force acts on it. The second law states that the force on an object is equal to its mass times its acceleration. And finally, the third law states that there is an equal and opposite reaction for every action.
