what is the mathematical representation of newton's 1st law
Answers
Answer:
There is no mathematical formula given for the newton's first law ,it states only 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.

Answer:
How to prove Newton’s First Law of motion from Newton’s Second law of motion – This physics lesson will show you how you can prove Newtons First (1st) Law of motion using second law of motion. To prove first first law, we need to know both law of motion.
Newton’s First Law – If external force applied on an object is zero, then if the object is moving will continue to move with the same speed and if the object is at rest will continue to be at rest.
Newton’s second law= The magnitude of the force applied on any object is equal to the product of mass and the acceleration acquired by the object i.e, F = m.a where m = mass of the object and a = acceleration of the object
To prove first from the second law just make F = 0 in the equation so will get m.a = 0
mass can’t be zero it means acceleration (a) = 0. There are only two cases when acceleration of an object is zero -one if the object is at rest and another if object is having uniform speed/velocity. It means in the absence of external force if the object is moving it will continue to move with same speed and if the object is at rest it will continue to be in rest- This is newton’s first law of motion.
