GENERAL KNOWLEDGE

Detailed explanation-1: -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.

Detailed explanation-2: -Section Summary. Newton’s first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion.

Detailed explanation-3: -Newton’s first law of motion is related to inertia because inertia is the tendency to resist change. Newton states that objects will resist change in their motion if not acted upon by a force, and this is the same concept of inertia. The more mass an object has, the greater its inertia.

Detailed explanation-4: -law of inertia, also called Newton’s first law, postulate in physics 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.

Detailed explanation-5: -Newton’s Second Law: F = ma: The net force F acting on an object with mass m and acceleration a is given by this expression. Newton’s first law is a special case of Newton’s second law when F = 0. Since m is not zero, acceleration must be zero.
