To every action is an equal and opposite reaction

Force is proportional to the ploduct of mass and acceleration
|
|

Everybody persists in its state of rest, or of motion in a straight line, unless acted upon by some force.

|
None of the above

Detailed explanation-1: -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-2: -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-3: -It is called the law of inertia because it tells that every material body has a property by virtue of which it resists the change in its state of rest or in its state of motion. This property is called inertia.
Detailed explanation-4: -Newton’s First law of motion states that an object will remain at rest or in uniform motion unless acted upon by an external force.
Detailed explanation-5: -Putting Newton’s 1st law of motion in simple words, a body will not start moving until and unless an external force acts on it. Once it is set in motion, it will not stop or change its velocity until and unless some force acts upon it once more. The first law of motion is sometimes also known as the law of inertia.
